Struct Be 

pub struct Be<T>(pub T);

Big-endian wrapper: encodes and decodes T most significant byte first.

Example

use wire_codec::{Be, Decode, Encode, ReadBuf, WriteBuf};

let mut out = [0u8; 4];
let mut buf = WriteBuf::new(&mut out);
Be(0xCAFE_u16).encode(&mut buf).unwrap();
Be(-2_i16).encode(&mut buf).unwrap();
assert_eq!(out, [0xCA, 0xFE, 0xFF, 0xFE]);

let mut r = ReadBuf::new(&out);
assert_eq!(Be::<u16>::decode(&mut r).unwrap().0, 0xCAFE);
assert_eq!(Be::<i16>::decode(&mut r).unwrap(), Be(-2));
