Snap for 7175096 from b2a603b29b393a52fce7bd046d66bd9ad656bed0 to sc-release Change-Id: I9c88bb8389c435b95fc8c2b2e16afa0dac40c8a7
This crate provides convenience methods for encoding and decoding numbers in either big-endian or little-endian order.
Dual-licensed under MIT or the UNLICENSE.
This crate works with Cargo and is on crates.io. Add it to your Cargo.toml
like so:
[dependencies] byteorder = "1"
If you want to augment existing Read
and Write
traits, then import the extension methods like so:
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());
no_std
cratesThis crate has a feature, std
, that is enabled by default. To use this crate in a no_std
context, add the following to your Cargo.toml
:
[dependencies] byteorder = { version = "1", default-features = false }
Note that as of Rust 1.32, the standard numeric types provide built-in methods like to_le_bytes
and from_le_bytes
, which support some of the same use cases.
