Enum zerocopy::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));
