Snap for 8426163 from 821d2a074bc11e3cd81c9156702d3ec6fb5f2228 to mainline-tzdata2-release Change-Id: I2b6e0b4ee2eca1ff9df920284f0ea42a2a2aa7dc
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:
extern crate byteorder; 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.
