Crate fixed_bigint

A fixed-size big integer implementation, unsigned only. FixedUInt implements a num_traits::PrimInt trait, mimicking built-in u8, u16 and u32 types. num_integer::Integer is also implemented.

Simple usage example:

use fixed_bigint::FixedUInt;

let a : FixedUInt<u8,2> = 200u8.into();
assert_eq!( a + a , 400u16.into() );
assert_eq!( a * &100u8.into(), 20000u16.into() )

Use Integer trait:

use fixed_bigint::FixedUInt;
use num_integer::Integer;

let a : FixedUInt<u8,2> = 400u16.into();
assert_eq!( a.is_multiple_of( &(8u8.into()) ) , true );
assert_eq!( a.gcd( &(300u16.into() )) , 100u8.into() );
assert_eq!( a.lcm( &(440u16.into() )) , 4400u16.into() );
