Table of Contents

Install

$ git clone git@github.com:jmcph4/spinifex-unsigned-varint.git
$ cd spinifex-unsigned-varint
$ cargo build

Usage

/* initialise from native integer types */
let some_number: u128 = 128;
let my_uvarint: UVarInt = UVarInt::new(some_number);

/* encode into byte vector */
let my_uvarint_bytes: Vec<u8> = my_uvarint
println!("{:#b}", my_uvarint_bytes); /* "[128, 1]" */

/* decode from byte vector */
let my_other_uvarint_bytes: Vec<u8> = vec![128, 128, 1];
let my_other_uvarint: UVarInt = UVarInt::from_bytes(my_other_uvarint_bytes).unwrap();
println!("{}", my_other_uvarint); /* "uv16384" */
