# Help
|
||||
|
||||
## Running the tests
|
||||
|
||||
Execute the tests with:
|
||||
|
||||
```bash
|
||||
$ cargo test
|
||||
```
|
||||
|
||||
All but the first test have been ignored. After you get the first test to
|
||||
pass, open the tests source file which is located in the `tests` directory
|
||||
and remove the `#[ignore]` flag from the next test and get the tests to pass
|
||||
again. Each separate test is a function with `#[test]` flag above it.
|
||||
Continue, until you pass every test.
|
||||
|
||||
If you wish to run _only ignored_ tests without editing the tests source file, use:
|
||||
|
||||
```bash
|
||||
$ cargo test -- --ignored
|
||||
```
|
||||
|
||||
If you are using Rust 1.51 or later, you can run _all_ tests with
|
||||
|
||||
```bash
|
||||
$ cargo test -- --include-ignored
|
||||
```
|
||||
|
||||
To run a specific test, for example `some_test`, you can use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test
|
||||
```
|
||||
|
||||
If the specific test is ignored, use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test -- --ignored
|
||||
```
|
||||
|
||||
To learn more about Rust tests refer to the online [test documentation][rust-tests].
|
||||
|
||||
[rust-tests]: https://doc.rust-lang.org/book/ch11-02-running-tests.html
|
||||
|
||||
## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit src/lib.rs Cargo.toml` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||
## Need to get help?
|
||||
|
||||
If you'd like help solving the exercise, check the following pages:
|
||||
|
||||
- The [Rust track's documentation](https://exercism.org/docs/tracks/rust)
|
||||
- [Exercism's support channel on gitter](https://gitter.im/exercism/support)
|
||||
- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
|
||||
|
||||
Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
|
||||
|
||||
## Rust Installation
|
||||
|
||||
Refer to the [exercism help page][help-page] for Rust installation and learning
|
||||
resources.
|
||||
|
||||
## Submitting the solution
|
||||
|
||||
Generally you should submit all files in which you implemented your solution (`src/lib.rs` in most cases). If you are using any external crates, please consider submitting the `Cargo.toml` file. This will make the review process faster and clearer.
|
||||
|
||||
## Feedback, Issues, Pull Requests
|
||||
|
||||
The GitHub [track repository][github] is the home for all of the Rust exercises. If you have feedback about an exercise, or want to help implement new exercises, head over there and create an issue. Members of the rust track team are happy to help!
|
||||
|
||||
If you want to know more about Exercism, take a look at the [contribution guide].
|
||||
|
||||
## Submitting Incomplete Solutions
|
||||
It's possible to submit an incomplete solution so you can see how others have completed the exercise.

# All Your Base
|
||||
|
||||
Welcome to All Your Base on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
Convert a number, represented as a sequence of digits in one base, to any other base.
|
||||
|
||||
Implement general base conversion. Given a number in base **a**,
|
||||
represented as a sequence of digits, convert it to base **b**.
|
||||
|
||||
## Note
|
||||
|
||||
- Try to implement the conversion yourself.
|
||||
Do not use something else to perform the conversion for you.
|
||||
|
||||
## About [Positional Notation](https://en.wikipedia.org/wiki/Positional_notation)
|
||||
|
||||
In positional notation, a number in base **b** can be understood as a linear
|
||||
combination of powers of **b**.
|
||||
|
||||
The number 42, *in base 10*, means:
|
||||
|
||||
(4 * 10^1) + (2 * 10^0)
|
||||
|
||||
The number 101010, *in base 2*, means:
|
||||
|
||||
(1 * 2^5) + (0 * 2^4) + (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (0 * 2^0)
|
||||
|
||||
The number 1120, *in base 3*, means:
|
||||
|
||||
(1 * 3^3) + (1 * 3^2) + (2 * 3^1) + (0 * 3^0)
|
||||
|
||||
I think you got the idea!
|
||||
|
||||
*Yes. Those three numbers above are exactly the same. Congratulations!*

# Help
|
||||
|
||||
## Running the tests
|
||||
|
||||
Execute the tests with:
|
||||
|
||||
```bash
|
||||
$ cargo test
|
||||
```
|
||||
|
||||
All but the first test have been ignored. After you get the first test to
|
||||
pass, open the tests source file which is located in the `tests` directory
|
||||
and remove the `#[ignore]` flag from the next test and get the tests to pass
|
||||
again. Each separate test is a function with `#[test]` flag above it.
|
||||
Continue, until you pass every test.
|
||||
|
||||
If you wish to run _only ignored_ tests without editing the tests source file, use:
|
||||
|
||||
```bash
|
||||
$ cargo test -- --ignored
|
||||
```
|
||||
|
||||
If you are using Rust 1.51 or later, you can run _all_ tests with
|
||||
|
||||
```bash
|
||||
$ cargo test -- --include-ignored
|
||||
```
|
||||
|
||||
To run a specific test, for example `some_test`, you can use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test
|
||||
```
|
||||
|
||||
If the specific test is ignored, use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test -- --ignored
|
||||
```
|
||||
|
||||
To learn more about Rust tests refer to the online [test documentation][rust-tests].
|
||||
|
||||
[rust-tests]: https://doc.rust-lang.org/book/ch11-02-running-tests.html
|
||||
|
||||
## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit src/lib.rs Cargo.toml` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||
## Need to get help?
|
||||
|
||||
If you'd like help solving the exercise, check the following pages:
|
||||
|
||||
- The [Rust track's documentation](https://exercism.org/docs/tracks/rust)
|
||||
- [Exercism's support channel on gitter](https://gitter.im/exercism/support)
|
||||
- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
|
||||
|
||||
Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
|
||||
|
||||
## Rust Installation
|
||||
|
||||
Refer to the [exercism help page][help-page] for Rust installation and learning
|
||||
resources.
|
||||
|
||||
## Submitting the solution
|
||||
|
||||
Generally you should submit all files in which you implemented your solution (`src/lib.rs` in most cases). If you are using any external crates, please consider submitting the `Cargo.toml` file. This will make the review process faster and clearer.
|
||||
|
||||
## Feedback, Issues, Pull Requests
|
||||
|
||||
The GitHub [track repository][github] is the home for all of the Rust exercises. If you have feedback about an exercise, or want to help implement new exercises, head over there and create an issue. Members of the rust track team are happy to help!
|
||||
|
||||
If you want to know more about Exercism, take a look at the [contribution guide].
|
||||
|
||||
## Submitting Incomplete Solutions
|
||||
It's possible to submit an incomplete solution so you can see how others have completed the exercise.

# Anagram
|
||||
|
||||
Welcome to Anagram on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
An anagram is a rearrangement of letters to form a new word.
|
||||
Given a word and a list of candidates, select the sublist of anagrams of the given word.
|
||||
|
||||
Given `"listen"` and a list of candidates like `"enlists" "google"
|
||||
"inlets" "banana"` the program should return a list containing
|
||||
`"inlets"`.
|
||||
|
||||
The solution is case insensitive, which means `"WOrd"` is the same as `"word"` or `"woRd"`. It may help to take a peek at the [std library](https://doc.rust-lang.org/std/primitive.char.html) for functions that can convert between them.
|
||||
|
||||
The solution cannot contain the input word. A word is always an anagram of itself, which means it is not an interesting result. Given `"hello"` and the list `["hello", "olleh"]` the answer is `["olleh"]`.
|
||||
|
||||
You are going to have to adjust the function signature provided in the stub in order for the lifetimes to work out properly. This is intentional: what's there demonstrates the basics of lifetime syntax, and what's missing teaches how to interpret lifetime-related compiler errors.
|
||||
|
||||
Try to limit case changes. Case changes are expensive in terms of time, so it's faster to minimize them.
|
||||
|
||||
If sorting, consider [sort_unstable](https://doc.rust-lang.org/std/primitive.slice.html#method.sort_unstable) which is typically faster than stable sorting. When applicable, unstable sorting is preferred because it is generally faster than stable sorting and it doesn't allocate auxiliary memory.

## Running the tests
|
||||
|
||||
Execute the tests with:
|
||||
|
||||
```bash
|
||||
$ cargo test
|
||||
```
|
||||
|
||||
All but the first test have been ignored. After you get the first test to
|
||||
pass, open the tests source file which is located in the `tests` directory
|
||||
and remove the `#[ignore]` flag from the next test and get the tests to pass
|
||||
again. Each separate test is a function with `#[test]` flag above it.
|
||||
Continue, until you pass every test.
|
||||
|
||||
If you wish to run _only ignored_ tests without editing the tests source file, use:
|
||||
|
||||
```bash
|
||||
$ cargo test -- --ignored
|
||||
```
|
||||
|
||||
If you are using Rust 1.51 or later, you can run _all_ tests with
|
||||
|
||||
```bash
|
||||
$ cargo test -- --include-ignored
|
||||
```
|
||||
|
||||
To run a specific test, for example `some_test`, you can use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test
|
||||
```
|
||||
|
||||
If the specific test is ignored, use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test -- --ignored
|
||||
```
|
||||
|
||||
To learn more about Rust tests refer to the online [test documentation][rust-tests].
|
||||
|
||||
[rust-tests]: https://doc.rust-lang.org/book/ch11-02-running-tests.html
|
||||
|
||||
## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit src/lib.rs Cargo.toml` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||
## Need to get help?
|
||||

|
||||
|
||||
- The [Rust track's documentation](https://exercism.org/docs/tracks/rust)
|
||||
- [Exercism's support channel on gitter](https://gitter.im/exercism/support)
|
||||
- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
|
||||
|
||||
Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
|
||||
|
||||
## Rust Installation
|
||||
|
||||
Refer to the [exercism help page][help-page] for Rust installation and learning
|
||||
resources.
|
||||
|
||||
## Submitting the solution
|
||||
|
||||
Generally you should submit all files in which you implemented your solution (`src/lib.rs` in most cases). If you are using any external crates, please consider submitting the `Cargo.toml` file. This will make the review process faster and clearer.
|
||||
|
||||

# Armstrong Numbers
|
||||
|
||||
Welcome to Armstrong Numbers on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
An [Armstrong number](https://en.wikipedia.org/wiki/Narcissistic_number) is a number that is the sum of its own digits each raised to the power of the number of digits.
|
||||
|
||||
For example:
|
||||
|
||||
- 9 is an Armstrong number, because `9 = 9^1 = 9`
|
||||
- 10 is *not* an Armstrong number, because `10 != 1^2 + 0^2 = 1`
|
||||
- 153 is an Armstrong number, because: `153 = 1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153`
|
||||
- 154 is *not* an Armstrong number, because: `154 != 1^3 + 5^3 + 4^3 = 1 + 125 + 64 = 190`
|
||||
|
||||
Write some code to determine whether a number is an Armstrong number.

||||

## For bonus points
|
||||
|
||||
Did you get the tests passing and the code clean? If you want to, these
|
||||
are some additional things you could try:
|
||||
|
||||
* Remove as much duplication as you possibly can.
|
||||
* Optimize for readability, even if it means introducing duplication.
|
||||
* If you've removed all the duplication, do you have a lot of
|
||||
conditionals? Try replacing the conditionals with polymorphism, if it
|
||||
applies in this language. How readable is it?
|
||||
|
||||
Then please share your thoughts in a comment on the submission. Did this
|
||||
experiment make the code better? Worse? Did you learn anything from it?

# Help
|
||||
|
||||
## Running the tests
|
||||
|
||||
Execute the tests with:
|
||||
|
||||
```bash
|
||||
$ cargo test
|
||||
```
|
||||
|
||||
All but the first test have been ignored. After you get the first test to
|
||||
pass, open the tests source file which is located in the `tests` directory
|
||||
and remove the `#[ignore]` flag from the next test and get the tests to pass
|
||||
again. Each separate test is a function with `#[test]` flag above it.
|
||||
Continue, until you pass every test.
|
||||
|
||||
If you wish to run _only ignored_ tests without editing the tests source file, use:
|
||||
|
||||
```bash
|
||||
$ cargo test -- --ignored
|
||||
```
|
||||
|
||||
If you are using Rust 1.51 or later, you can run _all_ tests with
|
||||
|
||||
```bash
|
||||
$ cargo test -- --include-ignored
|
||||
```
|
||||
|
||||
To run a specific test, for example `some_test`, you can use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test
|
||||
```
|
||||
|
||||
If the specific test is ignored, use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test -- --ignored
|
||||
```
|
||||
|
||||
To learn more about Rust tests refer to the online [test documentation][rust-tests].
|
||||
|
||||
[rust-tests]: https://doc.rust-lang.org/book/ch11-02-running-tests.html
|
||||
|
||||
## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit src/lib.rs Cargo.toml` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||
## Need to get help?
|
||||
|
||||
If you'd like help solving the exercise, check the following pages:
|
||||
|
||||
- The [Rust track's documentation](https://exercism.org/docs/tracks/rust)
|
||||
- [Exercism's support channel on gitter](https://gitter.im/exercism/support)
|
||||
- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
|
||||
|
||||
Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
|
||||
|
||||
## Rust Installation
|
||||
|
||||
Refer to the [exercism help page][help-page] for Rust installation and learning
|
||||
resources.
|
||||
|
||||
## Submitting the solution
|
||||
|
||||
Generally you should submit all files in which you implemented your solution (`src/lib.rs` in most cases). If you are using any external crates, please consider submitting the `Cargo.toml` file. This will make the review process faster and clearer.
|
||||
|
||||
## Feedback, Issues, Pull Requests
|
||||
|
||||
The GitHub [track repository][github] is the home for all of the Rust exercises. If you have feedback about an exercise, or want to help implement new exercises, head over there and create an issue. Members of the rust track team are happy to help!
|
||||

# Bob
|
||||
|
||||
Welcome to Bob on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
Bob is a lackadaisical teenager. In conversation, his responses are very limited.
|
||||
|
||||
Bob answers 'Sure.' if you ask him a question, such as "How are you?".
|
||||
|
||||
He answers 'Whoa, chill out!' if you YELL AT HIM (in all capitals).
|
||||
|
||||
He answers 'Calm down, I know what I'm doing!' if you yell a question at him.
|
||||
|
||||
He says 'Fine. Be that way!' if you address him without actually saying
|
||||
anything.
|
||||
|
||||
He answers 'Whatever.' to anything else.
|
||||
|
||||
Bob's conversational partner is a purist when it comes to written communication and always follows normal rules regarding sentence punctuation in English.

# Help

|
||||
## Running the tests
|
||||
|
||||
Execute the tests with:
|
||||
|
||||
```bash
|
||||
$ cargo test
|
||||
```
|
||||
|
||||
All but the first test have been ignored. After you get the first test to
|
||||
pass, open the tests source file which is located in the `tests` directory
|
||||
and remove the `#[ignore]` flag from the next test and get the tests to pass
|
||||
again. Each separate test is a function with `#[test]` flag above it.
|
||||
Continue, until you pass every test.
|
||||
|
||||
If you wish to run _only ignored_ tests without editing the tests source file, use:
|
||||
|
||||
```bash
|
||||
$ cargo test -- --ignored
|
||||
```
|
||||
|
||||
If you are using Rust 1.51 or later, you can run _all_ tests with
|
||||
|
||||
```bash
|
||||
$ cargo test -- --include-ignored
|
||||
```
|
||||
|
||||
To run a specific test, for example `some_test`, you can use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test
|
||||
```
|
||||
|
||||
If the specific test is ignored, use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test -- --ignored
|
||||
```
|
||||
|
||||
To learn more about Rust tests refer to the online [test documentation][rust-tests].

||||

||||

|
||||
|
||||
## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit src/lib.rs Cargo.toml` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||
## Need to get help?
|
||||
|
||||
If you'd like help solving the exercise, check the following pages:
|
||||
|
||||
- The [Rust track's documentation](https://exercism.org/docs/tracks/rust)
|
||||
- [Exercism's support channel on gitter](https://gitter.im/exercism/support)
|
||||
- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
|
||||
|
||||
Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
|
||||
|
||||
## Rust Installation
|
||||
|
||||
Refer to the [exercism help page][help-page] for Rust installation and learning
|
||||
resources.
|
||||
|
||||
## Submitting the solution
|
||||
|
||||
Generally you should submit all files in which you implemented your solution (`src/lib.rs` in most cases). If you are using any external crates, please consider submitting the `Cargo.toml` file. This will make the review process faster and clearer.
|
||||
|
||||
## Feedback, Issues, Pull Requests
|
||||
|
||||
The GitHub [track repository][github] is the home for all of the Rust exercises. If you have feedback about an exercise, or want to help implement new exercises, head over there and create an issue. Members of the rust track team are happy to help!
|
||||

# Clock
|
||||
|
||||
Welcome to Clock on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
Implement a clock that handles times without dates.
|
||||
|
||||
You should be able to add and subtract minutes to it.
|
||||
|
||||
Two clocks that represent the same time should be equal to each other.
|
||||
|
||||
You will also need to implement `.to_string()` for the `Clock` struct. We will be using this to display the Clock's state. You can either do it via implementing it directly or using the [Display trait](https://doc.rust-lang.org/std/fmt/trait.Display.html).
|
||||
|
||||
Did you implement `.to_string()` for the `Clock` struct?
|
||||
|
||||
If so, try implementing the
|
||||
[Display trait](https://doc.rust-lang.org/std/fmt/trait.Display.html) for `Clock` instead.
|
||||
|
||||
Traits allow for a common way to implement functionality for various types.
|
||||
|
||||
For additional learning, consider how you might implement `String::from` for the `Clock` type.
|
||||
You don't have to actually implement this—it's redundant with `Display`, which is generally the
|
||||
better choice when the destination type is `String`—but it's useful to have a few type-conversion
|
||||
traits in your toolkit.

# Help
|
||||
|
||||
## Running the tests
|
||||
|
||||
Execute the tests with:
|
||||
|
||||
```bash
|
||||
$ cargo test
|
||||
```
|
||||
|
||||
All but the first test have been ignored. After you get the first test to
|
||||
pass, open the tests source file which is located in the `tests` directory
|
||||
and remove the `#[ignore]` flag from the next test and get the tests to pass
|
||||
again. Each separate test is a function with `#[test]` flag above it.
|
||||
Continue, until you pass every test.
|
||||
|
||||
If you wish to run _only ignored_ tests without editing the tests source file, use:
|
||||
|
||||
```bash
|
||||
$ cargo test -- --ignored
|
||||
```
|
||||
|
||||
If you are using Rust 1.51 or later, you can run _all_ tests with
|
||||
|
||||
```bash
|
||||
$ cargo test -- --include-ignored
|
||||
```
|
||||
|
||||
To run a specific test, for example `some_test`, you can use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test
|
||||
```
|
||||
|
||||
If the specific test is ignored, use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test -- --ignored
|
||||
```
|
||||
|
||||
To learn more about Rust tests refer to the online [test documentation][rust-tests].
|
||||
|
||||
[rust-tests]: https://doc.rust-lang.org/book/ch11-02-running-tests.html
|
||||
|
||||
## Submitting your solution
|
||||
|
||||
You can submit your solution using the `exercism submit src/lib.rs Cargo.toml` command.
|
||||
This command will upload your solution to the Exercism website and print the solution page's URL.
|
||||
|
||||
It's possible to submit an incomplete solution which allows you to:
|
||||
|
||||
- See how others have completed the exercise
|
||||
- Request help from a mentor
|
||||
|
||||
## Need to get help?
|
||||
|
||||
If you'd like help solving the exercise, check the following pages:
|
||||
|
||||
- The [Rust track's documentation](https://exercism.org/docs/tracks/rust)
|
||||
- [Exercism's support channel on gitter](https://gitter.im/exercism/support)
|
||||
- The [Frequently Asked Questions](https://exercism.org/docs/using/faqs)
|
||||
|
||||
Should those resources not suffice, you could submit your (incomplete) solution to request mentoring.
|
||||
|
||||
## Rust Installation
|
||||
|
||||
Refer to the [exercism help page][help-page] for Rust installation and learning
|
||||
resources.
|
||||
|
||||
## Submitting the solution
|
||||
|
||||
Generally you should submit all files in which you implemented your solution (`src/lib.rs` in most cases). If you are using any external crates, please consider submitting the `Cargo.toml` file. This will make the review process faster and clearer.
|
||||
|
||||

# Gigasecond
|
||||
|
||||
Welcome to Gigasecond on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
Given a moment, determine the moment that would be after a gigasecond
|
||||
has passed.
|
||||
|
||||
A gigasecond is 10^9 (1,000,000,000) seconds.
|
||||
|
||||
If you're unsure what operations you can perform on `PrimitiveDateTime` take a look at the [time crate](https://docs.rs/time) which is listed as a dependency in the `Cargo.toml` file for this exercise.

# Grade School
|
||||
|
||||
Welcome to Grade School on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
|
||||
## Instructions
|
||||
|
||||
Given students' names along with the grade that they are in, create a roster
|
||||
for the school.
|
||||
|
||||
In the end, you should be able to:
|
||||
|
||||
- Add a student's name to the roster for a grade
|
||||
- "Add Jim to grade 2."
|
||||
- "OK."
|
||||
- Get a list of all students enrolled in a grade
|
||||
- "Which students are in grade 2?"
|
||||
- "We've only got Jim just now."
|
||||
- Get a sorted list of all students in all grades. Grades should sort
|
||||
as 1, 2, 3, etc., and students within a grade should be sorted
|
||||
alphabetically by name.
|
||||
- "Who all is enrolled in school right now?"
|
||||
- "Let me think. We have
|
||||
Anna, Barb, and Charlie in grade 1,
|
||||
Alex, Peter, and Zoe in grade 2
|
||||
and Jim in grade 5.
|
||||
So the answer is: Anna, Barb, Charlie, Alex, Peter, Zoe and Jim"
|
||||
|
||||
Note that all our students only have one name. (It's a small town, what
|
||||
do you want?)
|
||||
|
||||
## For bonus points
|
||||
|
||||
Did you get the tests passing and the code clean? If you want to, these
|
||||
are some additional things you could try:
|
||||
|
||||
- If you're working in a language with mutable data structures and your
|
||||
implementation allows outside code to mutate the school's internal DB
|
||||
directly, see if you can prevent this. Feel free to introduce additional
|
||||
tests.
|
||||
|
||||
Then please share your thoughts in a comment on the submission. Did this
|
||||
experiment make the code better? Worse? Did you learn anything from it?

# Help
|
||||
|
||||
## Running the tests
|
||||
|
||||
Execute the tests with:
|
||||
|
||||
```bash
|
||||
$ cargo test
|
||||
```
|
||||
|
||||
All but the first test have been ignored. After you get the first test to
|
||||
pass, open the tests source file which is located in the `tests` directory
|
||||
and remove the `#[ignore]` flag from the next test and get the tests to pass
|
||||
again. Each separate test is a function with `#[test]` flag above it.
|
||||
Continue, until you pass every test.
|
||||
|
||||
If you wish to run _only ignored_ tests without editing the tests source file, use:
|
||||
|
||||
```bash
|
||||
$ cargo test -- --ignored
|
||||
```
|
||||
|
||||
If you are using Rust 1.51 or later, you can run _all_ tests with
|
||||
|
||||
```bash
|
||||
$ cargo test -- --include-ignored
|
||||
```
|
||||
|
||||
To run a specific test, for example `some_test`, you can use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test
|
||||
```
|
||||
|
||||
If the specific test is ignored, use:
|
||||
|
||||
```bash
|
||||
$ cargo test some_test -- --ignored
|
||||
```
|
||||
|
||||
To learn more about Rust tests refer to the online [test documentation][rust-tests].

# Hints
|
||||
|
||||
## General
|
||||
|
||||
## 1. Implement the `new()` method
|
||||
|
||||
- The `new()` method receives the arguments we want to instantiate a `User` instance with. It should return an instance of `User` with the specified name, age, and weight.
|
||||
|
||||
- See [here](https://doc.rust-lang.org/book/ch05-01-defining-structs.html) for additional examples on defining and instantiating structs.
|
||||
|
||||
## 2. Implement the getter methods
|
||||
|
||||
- The `name()`, `age()`, and `weight()` methods are getters. In other words, they are responsible for returning the corresponding field from a struct instance.
|
||||
|
||||
- Notice that the `name` method returns a `&str` when the `name` field on the `User` struct is a `String`. How can we get `&str` and `String` to play nice with each other?
|
||||
|
||||
- There's no need to use a `return` statement in Rust unless you expressly want a function or method to return early. Otherwise, it's more idiomatic to utilize an _implicit_ return by omitting the semicolon for the result we want a function or method to return. It's not _wrong_ to use an explicit return, but it's cleaner to take advantage of implicit returns where possible.
|
||||
|
||||
```rust
|
||||
fn foo() -> i32 {
|
||||
1
|
||||
}
|
||||
```
|
||||
|
||||
- See [here](https://doc.rust-lang.org/book/ch05-03-method-syntax.html) for some more examples of defining methods on structs.
|
||||
|
||||
## 3. Implement the setter methods
|
||||
|
||||
- The `set_age()` and `set_weight()` methods are setters, responsible for updating the corresponding field on a struct instance with the input argument.
|
||||
|
||||
- As the signatures of these methods specify, the setter methods shouldn't return anything.

# Health Statistics
|
||||
|
||||
Welcome to Health Statistics on Exercism's Rust Track.
|
||||
If you need help running the tests or submitting your code, check out `HELP.md`.
|
||||
If you get stuck on the exercise, check out `HINTS.md`, but try and solve it without using those first :)
|
||||
|
||||
## Introduction
|
||||
|
||||
It is often useful to group a collection of items together, and handle those groups as units. In Rust, we call such a group a struct, and each item one of the struct's fields. A struct defines the general set of fields available, but a particular example of a struct is called an instance.
|
||||
|
||||
Furthermore, structs can have methods defined on them, which have access to the fields. The struct itself in that case is referred to as `self`. When a method uses `&mut self`, the fields can be changed, or mutated. When a method uses `&self`, the fields cannot be changed: they are immutable. Controlling mutability helps the borrow-checker ensure that entire classes of concurrency bug just don't happen in Rust.
|
||||
|
||||
In this exercise, you'll be implementing two kinds of methods on a struct. The first are generally known as getters: they expose the struct's fields to the world, without letting anyone else mutate that value. In Rust, these methods idiomatically share the name of the field they expose, i.e., if we have a getter method that fetches a struct field called `name`, the method would simply be called `name()`.
|
||||
|
||||
You'll also be implementing methods of another type, generally known as setters. These change the value of the field. Setters aren't very common in Rust--if a field can be freely modified, it is more common to just make it public--but they're useful if updating the field should have side effects, or for access control: a setter marked as `pub(crate)` allows other modules within the same crate to update a private field, which can't be affected by the outside world.
|
||||
|
||||
Structs come in three flavors: structs with named fields, tuple structs, and unit structs. For this concept exercise, we'll be exploring the first variant: structs with named fields.
|
||||
|
||||
Structs are defined using the `struct` keyword, followed by the capitalized name of the type the struct is describing:
|
||||
|
||||
```rust
|
||||
struct Item {}
|
||||
```
|
||||
|
||||
Additional types are then brought into the struct body as _fields_ of the struct, each with their own type:
|
||||
|
||||
```rust
|
||||
struct Item {
|
||||
name: String,
|
||||
weight: f32,
|
||||
worth: u32,
|
||||
}
|
||||
```
|
||||
|
||||
Lastly, methods can be defined on structs inside of an `impl` block:
|
||||
|
||||
```rust
|
||||
impl Item {
|
||||
// initializes and returns a new instance of our Item struct
|
||||
fn new() -> Self {
|
||||
unimplemented!()
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
With that brief introduction to the syntax of structs out of the way, go ahead and take a look at the [instructions](instructions.md) for this exercise!
|
||||
|
||||
## Instructions
|
||||
|
||||
You're working on implementing a health-monitoring system. As part of that, you need to keep track of users' health statistics.
|
||||
|
||||
You'll start with some stubbed functions in an `impl` block as well as the following struct definition:
|
||||
|
||||
```rust
|
||||
pub struct User {
|
||||
name: String,
|
||||
age: u32,
|
||||
weight: f32,
|
||||
}
|
||||
```
|
||||
|
||||
Your goal is to implement the stubbed out methods on the `User` `struct` defined in the `impl` block.
|
||||
|
||||
For example, the `new` method should return an instance of the `User` struct with the specified name, age, and weight values.
|
||||
|
||||
```rust
|
||||
let mut bob = User::new(String::from("Bob"), 32, 155.2);
|
||||
// Returns: a User with name "Bob", age 32, and weight 155.2
|
||||
```
|
||||
|
||||
The `weight` method should return the weight of the `User`.
|
||||
|
||||
```rust
|
||||
bob.weight();
|
||||
// Returns: 155.2
|
||||
```
|
||||
|
||||
The `set_age` method should set the age of the `User`.
|
||||
|
||||
```rust
|
||||
bob.set_age(33);
|
||||
// Updates Bob's age to 33; happy birthday Bob!
|
||||
```
|
||||
|
||||
Have fun!
