Function kernel::types::bit

pub const fn bit<T: Copy>(index: T) -> Bit<T>

Creates a bit mask with a single bit set.

Examples

let mut x = 0xfeu32;

assert_eq!(x & bit(0), 0);
assert_eq!(x & bit(1), 2);
assert_eq!(x & bit(2), 4);
assert_eq!(x & bit(3), 8);

x |= bit(0);
assert_eq!(x, 0xff);

x &= !bit(1);
assert_eq!(x, 0xfd);

x &= !bit(7);
assert_eq!(x, 0x7d);

let y: u64 = bit(34).into();
assert_eq!(y, 0x400000000);

assert_eq!(y | bit(35), 0xc00000000);
