Module xor_distance_exercise::bitops

Miscellaneous bit operations for any [Integer].

Examples

extern crate xor_distance_exercise;

use xor_distance_exercise::bitops::{is_flag, is_bit_set, is_flag_set, set_bit, set_flag};

let x = 0b1000_0000_1001_1010;
let flag = 0b1000_0000;

assert!(is_flag(flag));
assert!(is_bit_set(flag, 7));
assert!(is_flag_set(x, flag));

let mut y = 0b1000_0000_0001_1010;

set_flag(&mut y, flag);
assert_eq!(0b1000_0000_1001_1010, y);

set_bit(&mut y, 0);
assert_eq!(0b1000_0000_1001_1011, y);

Functions

is_bit_set

Returns whether the bit on specified bit index is set to “1”.

is_flag

Returns whether this number only has one bit set.

is_flag_set

Returns whether the given flag is set.

set_bit

Set bit to “1” for specified bit index. Indexed from zero.

set_flag

Set flag.
