lazy-bytes-cast

This crate provides simple methods to cast from and into byte arrays.

Note

The crates will not take care of byte order for you. Cuz lazy.

Usage

Slice integer as bytes

use lazy_bytes_cast::slice::{ByteSlice, ByteIndex};

fn main() {
    let some_int = 666;

    for (idx, byte) in some_int.byte_slice().iter().enumerate() {
        assert_eq!(some_int.byte(idx).unwrap(), *byte);
        println!("bytes[{}]={}", idx, byte);
    }
}

Cast bytes to integer

use lazy_bytes_cast::from::{bytes_cast};

fn main() {
    let bytes = vec![127, 150, 152, 0];

    if let Some(int) = bytes_cast::<u32>(&bytes) {
        println!("bytes={}", int);
    } else {
        println!("Couldn't extract integer from bytes");
    }
}

Cast integer to bytes

use lazy_bytes_cast::to::{ToBytesCast};

fn main() {
    let some_int = 666;

    let bytes = some_int.to_bytes();

    println!("bytes={:?}", bytes);
}
