pub enum LittleEndian {}
Expand description
Defines little-endian serialization.
Note that this type has no value constructor. It is used purely at the type level.
Examples
Write and read u32
numbers in little endian order:
use byteorder::{ByteOrder, LittleEndian};
let mut buf = [0; 4];
LittleEndian::write_u32(&mut buf, 1_000_000);
assert_eq!(1_000_000, LittleEndian::read_u32(&buf));
