# Luhn: Using the From Trait

Before doing this exercise you should probably do the original Luhn exercise. If you have not completed Luhn, you can get it by running the command:

> `exercism fetch rust luhn`

In the original Luhn exercise you only validated strings, but the Luhn algorithm can be applied to integers as well.

In this exercise you'll implement the [From trait](https://doc.rust-lang.org/std/convert/trait.From.html) to convert strings, strs and unsigned integers into a Struct that performs the validation.
