}
Expand description

Provides bit indexing operations.

This trait defines functions for accessing single bits to determine whether they are set and for accessing ranges of bits to extract the value they contain.

Examples

use quark::BitIndex;

let value: u32 = 0xe01a3497;

let s = value.bit(20);
assert!(s);
let rd = value.bits(16..20);
assert_eq!(rd, 10);
let rn = value.bits(12..16);
assert_eq!(rn, 3);
let rs = value.bits(8..12);
assert_eq!(rs, 4);
let rm = value.bits(0..4);
assert_eq!(rm, 7);

Required Methods

Returns whether the specified bit is set.

Returns the bits contained in the specified bit range.
