Struct solid::int::Uint

pub struct Uint<'a, const N: usize, const M: usize>(pub &'a [u8; M])
 where
    [u8; M]: LengthAtMost32,
    [u8; M]: LengthAtLeast1;

A simpler structure to represent all Solidity uint<N> types using const generics

Due to const generics not being stable, the user would be required to specify both the size in bites and bytes (N and M respectively) for each type. N MUST be equal to M * 8.

let int256 = Uint<256, 32>(&[0u8; 32]);
let int200 = Uint<200, 25>(&[0u8; 25]);

Note: It's very easy to missuse this structure because the even though the struct requries both the number of bits and bytes to be supplied, it cannot validate that N = M * 8 which is why it's not recommend to use this until const generics are stable.
