Crate uleb128

Extension traits that allow for the reading and writing of unsigned LEB128 integer values.

Read

To read unsigned LEB128 integers, do so through the ReadULeb128Ext extension trait. Importing this trait into a file allows for reading unsigned integers encoded in unsigned LEB128 from any type that implements Read.

use std::io::Cursor;
use uleb128::ReadULeb128Ext;

let mut rdr = Cursor::new(vec![0b1000_0000, 0b0000_0001]);
assert_eq!(128, rdr.read_uleb128_u32().unwrap());

Write

To write unsigned integers as unsigned LEB128, do so through the WriteULeb128Ext extension trait. Importing this trait into a file allows for writing unsigned integers as unsigned LEB128 from any type that implements Write.

use uleb128::WriteULeb128Ext;

let mut wtr = vec![];
wtr.write_uleb128_u32(128).unwrap();

assert_eq!(wtr, vec![0b1000_0000, 0b0000_0001]);

Enums
