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.**

### Documentation
[http://burntsushi.net/rustdoc/byteorder/](http://burntsushi.net/rustdoc/byteorder/).
The documentation includes examples.
### Installation
This crate works with Cargo and is on
[crates.io](https://crates.io/crates/byteorder). The package is regularly
updated. Add is to your `Cargo.toml` like so:
```toml
[dependencies]
byteorder = "*"
```
If you want to augment existing `Reader` and `Writer` types, then import the
extension methods like so:
```rust
extern crate byteorder;
use byteorder::{ReaderBytesExt, WriterBytesExt, BigEndian, LittleEndian};
```
For example:
```rust
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());
```
