bittersweet

Bittersweet is a library for bit manipulation.

Motivation

Bit-wise operations are often used in low-level programming and it sometimes contains magical bugs. I want to manipulate bits with more

• type-safe
• well-tested
• well-documented
• fast and efficient

Usage

Installation

You can install this library via cargo.

$ cargo add bittersweet

Or you can add this to your Cargo.toml manually.

Example

use bittersweet::bitline::{Bitline, Bitline8};
fn main() {
    let t = 0b00111000_u8 as Bitline8;
    if t.includes(0b00110000_u8) {
        println!("Yes!");
    }
}

Supported bitline length

Following Bitline traits are implemented for u8, u16, u32, u64, u128. So these operations keep zero-cost abstraction.

• Bitline8 ... 8 bits (u8)
• Bitline16 ... 16 bits (u16)
• Bitline32 ... 32 bits (u32)
• Bitline64 ... 64 bits (u64)
• Bitline128 ... 128 bits (u128)
