Bit

bit is a library which provides some useful helpers for dealing with bits and bit ranges. For now it's just a rewrite of rust-bit-field crate, but more features are planned. Some of them could be:

• Support for arrays and slices.
• bitflags-like functionality.

Usage

Add to your Cargo.toml:

[dependencies]
bit = "0.1"

And add to your code:

extern crate bit;
use bit::BitIndex;

Example

extern crate bit;
use bit::BitIndex;

fn main() {
    let mut value = 0b11010110u8;

    // 8
    println!("{}", u8::bit_length());

    // true
    println!("{}", value.bit(1));

    // 0b10
    println!("{:#b}", value.bit_range(0..2));

    value
        .set_bit(3, true)
        .set_bit(2, false)
        .set_bit_range(5..8, 0b001);

    // 0b111010
    println!("{:#b}", value);
}

lib.rs:

This crate adds simple bit-manipulation helpers in a convenient trait. Also, it implements them for the unsigned primitive types.
