# Allergies

Given a person's allergy score, determine whether or not they're allergic to a given item, and their full list of allergies.

An allergy test produces a single numeric score which contains the
information about all the allergies the person has (that they were
tested for).

The list of items (and their value) that were tested are:

* eggs (1)
* peanuts (2)
* shellfish (4)
* strawberries (8)
* tomatoes (16)
* chocolate (32)
* pollen (64)
* cats (128)

So if Tom is allergic to peanuts and chocolate, he gets a score of 34.

Now, given just that score of 34, your program should be able to say:

- Whether Tom is allergic to any one of those allergens listed above.
- All the allergens Tom is allergic to.

Note: a given score may include allergens **not** listed above (i.e.
allergens that score 256, 512, 1024, etc.).  Your program should
ignore those components of the score.  For example, if the allergy
score is 257, your program should only report the eggs (1) allergy.


## 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.
