# 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.
|
||
|
|
|
||
|
|
## Rust Traits for `.to_string()`
|
||
|
|
|
||
|
|
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][display-trait].
|
||
|
|
|
||
|
|
If so, try implementing the [Display trait][display-trait] 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.
