Lib.rs

Helper library for reading/writing variable length integers

use varint_bytes::{GetVarInt, PutVarInt};
use bytes::{BytesMut};

let mut bytes = &[0b1010_1100, 0b0000_0010][..];
let num: u32 = bytes.get_varint();
assert_eq!(num, 300);

let mut bytes = BytesMut::new();
bytes.put_varint(300 as u32);
assert_eq!(bytes[..], [0b1010_1100, 0b0000_0010][..]);

Advantages:

• Misuse resistant - won't read more than the maximum size of the output type or past the input
• Uses tokio/bytes's Buf
• no_std and forbid(unsafe_code)
