byteorder 0.2.13

Library for reading/writing numbers in big-endian and little-endian. failed to build byteorder-0.2.13
Please check build logs and if you believe this is' fault, report into this issue report.

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.

This crate currently supports both the std::io and std::old_io modules.

This crate works with Cargo and is on The package is regularly updated. Add is to your Cargo.toml like so:

byteorder = "*"

If you want to augment existing Reader and Writer types, then import the extension methods like so:

extern crate byteorder;

use byteorder::{ReaderBytesExt, WriterBytesExt, BigEndian, LittleEndian};

Or use the ReadBytesExt/WriteBytesExt traits if you're using the new std::io module.

For example:

use std::old_io::MemReader;
use byteorder::{BigEndian, ReaderBytesExt};

let mut rdr = MemReader::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());
