# Proverb
|
|
|
|
For want of a horseshoe nail, a kingdom was lost, or so the saying goes. Output
|
|
the full text of this proverbial rhyme:
|
|
|
|
> For want of a nail the shoe was lost.
|
|
> For want of a shoe the horse was lost.
|
|
> For want of a horse the rider was lost.
|
|
> For want of a rider the message was lost.
|
|
> For want of a message the battle was lost.
|
|
> For want of a battle the kingdom was lost.
|
|
> And all for the want of a horseshoe nail.

## Rust Installation
|
|
|
|
Refer to the [exercism help page][help-page] for Rust installation and learning
|
|
resources.
|
|
|
|
## Writing the Code
|
|
|
|
Execute the tests with:
|
|
|
|
```bash
|
|
$ cargo test
|
|
```
|
|
|
|
All but the first test have been ignored. After you get the first test to
|
|
pass, remove the ignore flag (`#[ignore]`) from the next test and get the tests
|
|
to pass again. The test file is located in the `tests` directory. You can
|
|
also remove the ignore flag from all the tests to get them to run all at once
|
|
if you wish.
|
|
|
|
Make sure to read the [Crates and Modules](https://doc.rust-lang.org/stable/book/crates-and-modules.html) chapter if you
|
|
haven't already, it will help you with organizing your files.
