This crate provides convenience methods for encoding and decoding numbers in either big-endian or little-endian order. This is meant to replace the old methods defined on the standard library Reader
and Writer
traits.

The documentation includes examples.
This crate works with Cargo and is on crates.io. The package is regularly updated. Add it to your Cargo.toml
like so:
[dependencies] byteorder = "0.4"
If you want to augment existing Read
and Write
traits, then import the extension methods like so:
extern crate byteorder; use byteorder::{ReadBytesExt, WriteBytesExt, BigEndian, LittleEndian};
For example:
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());
