Snap for 8564071 from be59e71aea50702c7f0fbdb5d015eb14129c53fc to mainline-extservices-release Change-Id: I8f385b9af26ca2ee290a8ab1a7452006aad0adb2
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.
