const-twiddle
Bitwise utility functions
const-twiddle is a set of bitwise utility functions designed to be similar to twiddle.
It is also compatible with const and supports #![no_std] out of the box.
Usage
Add const-twiddle to your Cargo.toml file:
[dependencies]
const-twiddle = "0.1"
const-twiddle = "0.1"
Usage outside of const:
use const_twiddle::Twiddle;
fn test() {
let mut x = 5;
x.set_bit(0, false);
assert_eq!(x, 4);
assert_eq!(x.with_bit(0, true), 5);
assert_eq!(x.bit(0), false);
}
fn test() {
let mut x = 5;
x.set_bit(0, false);
assert_eq!(x, 4);
assert_eq!(x.with_bit(0, true), 5);
assert_eq!(x.bit(0), false);
}
Usage inside const contexts:
use const_twiddle::ConstU32;
const fn test() {
// Traits are not supported in const yet
let x = ConstU32(5).with_bit(0, false).0; //x = 4
}
const fn test() {
// Traits are not supported in const yet
let x = ConstU32(5).with_bit(0, false).0; //x = 4
}
