Crate byteorder [] [src]

This crate provides convenience methods for encoding and decoding numbers in either big-endian or little-endian order.

The organization of the crate is pretty simple. A trait, ByteOrder, specifies byte conversion methods for each type of number in Rust (sans numbers that have a platform dependent size like usize and isize). Two types, BigEndian and LittleEndian implement these methods. Finally, ReadBytesExt and WriteBytesExt provide convenience methods available to all types that implement Read and Write.

Examples

Read unsigned 16 bit big-endian integers from a Read type:

use std::io::Cursor;
use byteorder::{BigEndian, ReadBytesExt};

let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
// Note that we use type parameters to indicate which kind of byte order
// we want!
assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());

Write unsigned 16 bit little-endian integers to a Write type:

use byteorder::{LittleEndian, WriteBytesExt};

let mut wtr = vec![];
wtr.write_u16::<LittleEndian>(517).unwrap();
wtr.write_u16::<LittleEndian>(768).unwrap();
assert_eq!(wtr, vec![5, 2, 0, 3]);
