### Installation
|
||
|
|
|
||
|
|
This crate works with Cargo and is on
|
||
|
|
[crates.io](https://crates.io/crates/byteorder). Add it to your `Cargo.toml`
|
||
|
|
like so:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[dependencies]
|
||
|
|
byteorder = "1"
|
||
|
|
```
|
||
|
|
|
||
|
|
If you want to augment existing `Read` and `Write` traits, then import the
|
||
|
|
extension methods like so:
|
||
|
|
|
||
|
|
```rust
|
||
|
|
extern crate byteorder;
|
||
|
|
|
||
|
|
use byteorder::{ReadBytesExt, WriteBytesExt, BigEndian, LittleEndian};
|
||
|
|
```
|
||
|
|
|
||
|
|
For example:
|
||
|
|
|
||
|
|
```rust
|
||
|
|
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());
|
||
|
|
```
|
||
|
|
|
||
|
|
