# [−] [src] Enum byteorder::LittleEndian

    pub enum LittleEndian {}

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));
