Extends ReadBytes with functions for reading numbers.

Examples

Read a u16 from a buffer using native endianness:

use byteio::ReadBytesExt;

fn main() {
    let mut buf: &[u8] = &[0, 1];

    #[cfg(target_endian = "little")]
    let a = buf.read_u16_le();
    #[cfg(target_endian = "big")]
    let a = buf.read_u16_be();

    assert!(buf.is_empty());
}
