Aint

Aint is a crate implementing integers of non-standard bit widths between 1 and 127. These integer types are represented by the next largest built-in Rust integer, but are bounded to the range and behaviors of the advertised bit width. That is, T::MIN and T::MAX, are what would be expected for the integer T with N bits, and similarly, wrapping, saturating, and overflow behaviors match what would be expected for a hypothetical built-in integer T with N bits.

Example

fn add(a: i13, b: i13) -> i13 {
    a + b
}

let x = i13!(100);
let y = add(x, i13!(-42));
assert_eq!(y, i13!(58));
