intbits

Easy access to individual bits of integers

use intbits::Bits;

assert_eq!(2.bit(0), false);
assert_eq!(2.bit(1), true);
assert_eq!(2.bit(2), false);

assert_eq!(0b1011u32.bits(0..2), 0b11);
assert_eq!(0b1011u32.bits(2..4), 0b10);

assert_eq!(0xFFu8.with_bit(3, false), 0xF7);
assert_eq!(0xFFu8.with_bits(4..8, 3), 0x3F);

See the documentation.

lib.rs:

This crates provides two functions for accessing the individual bits of integers:

• .bit(i) to get one specific bit.
• .bits(i..j) to get a range of bits.

It also provides similar functions for changing specific bits of integers:

• .set_bit(i, bit) to set one specific bit.
• .set_bits(i..j, bits) to set a range of bits.

These variants return a new integer, instead of modifying it:

• .with_bit(i, bit)
• .with_bits(i..j, bits)

Example

use intbits::Bits;

assert_eq!(2.bit(0), false);
assert_eq!(2.bit(1), true);
assert_eq!(2.bit(2), false);

assert_eq!(0b1011u32.bits(0..2), 0b11);
assert_eq!(0b1011u32.bits(2..4), 0b10);

assert_eq!(0xFFu8.with_bit(3, false), 0xF7);
assert_eq!(0xFFu8.with_bits(4..8, 3), 0x3F);
