Crate is_in 

is_in

A small crate featuring a nice way to check if a value is in an array.

Basic usage.

use is_in::IsIn;

fn main() {
    let data: &[u8; 3] = [1, 2, 3];
    let two: u8 = 2;
    println!("{}", two.is_in(data)); // prints true
}```
The crate provides implementations on most primitives (all unsigned integers, all signed integers, floats, and chars).
