Crate lebe 

Dead simple endianness conversions. The following operations are implemented on u8, i8, u16, i16, u32, i32, u64, i64, u128, i128, f32, f64:

Read Numbers

use lebe::prelude::*;
let mut reader: &[u8] = &[0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];

let number : u64 = reader.read_from_little_endian()?;
let number = u64::read_from_big_endian(&mut reader)?;

Read Slices

use std::io::Read;
use lebe::prelude::*;
let mut reader: &[u8] = &[0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15];

let mut numbers: &mut [u64] = &mut [0, 0];
reader.read_from_little_endian_into(numbers)?;

Write Numbers

use std::io::Read;
use lebe::prelude::*;
let mut writer: Vec<u8> = Vec::new();

let number: u64 = 1237691;
writer.write_as_big_endian(&number)?;

Write Slices

use std::io::Write;
use lebe::prelude::*;
let mut writer: Vec<u8> = Vec::new();

let numbers: &[u64] = &[1_u64, 234545_u64];
writer.write_as_little_endian(numbers)?;

Modules

io

Easily write primitives and slices of primitives to binary std::io::Write streams and easily read from binary std::io::Read streams.

prelude

Exports some of the most common types.

Traits

Endian

Represents values that can swap their bytes to reverse their endianness.
