bint-rs
Bounded Integer in Rust
Usage
Original immutable Bint:
extern crate bint;
let b: bint::Bint = bint::Bint {value: 5, boundary: 6 };
let c: Bint = b.up();
let d: Bint = c.up();
println!("{} {} {}", b, c, d); // Prints 5 0 1
New and improved BintCell:
use bint::BintCell;
let b = BintCell::new(6);
b.down();
assert_eq!(5, b.value());
b.up();
b.up();
b.up();
assert_eq!(2, b.value());
