Function usize_plus_i 

pub fn usize_plus_i<T>(u: usize, i: T) -> usize
where
    T: TryFrom<usize, Error: Debug> + Add<Output = T>,
    usize: TryFrom<T, Error: Debug>,

Adds generic type to usize. Can panic if the values are outside the range of the given types.

use aoclib_rs::usize_plus_i;

let i: i64 = 23;
assert_eq!(usize_plus_i(5, i), 28);

let i: i64 = -2;
assert_eq!(usize_plus_i(5, i), 3);

// let i: i64 = -8;
// usize_plus_i(5, i);
// panics: -3 is an invalid usize

// let i: i8 = 5;
// usize_plus_i(12345, i);
// panics: 12345 is an invalid i8
