exercism/rust/nth-prime

Nth Prime

Given a number n, determine what the nth prime is.

By listing the first six prime numbers: 2, 3, 5, 7, 11, and 13, we can see that the 6th prime is 13.

If your language provides methods in the standard library to deal with prime numbers, pretend they don't exist and implement them yourself.

Rust Installation

Refer to the exercism help page for Rust installation and learning resources.

Writing the Code

Execute the tests with:

$ 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 chapter if you haven't already, it will help you with organizing your files.
