Go implementation of [Little Endian Base 128 codec](https://en.wikipedia.org/wiki/LEB128).

## Install
```bash
$ go get -u ekyu.moe/leb128
# or better
$ dep ensure -add ekyu.moe/leb128
```

## Example
```go
package main

import (
    "fmt"

"ekyu.moe/leb128"
)

func main() {
    // Notes: These specs are taken from https://en.wikipedia.org/wiki/LEB128
    // Encode unsigned LEB128
    fmt.Printf("%x\n", leb128.AppendUleb128(nil, 624485)) //=> e58e26

// Encode signed LEB128
    fmt.Printf("%x\n", leb128.AppendSleb128(nil, -624485)) //=> 9bf159

// Decode unsigned LEB128, n is the number of bytes read
    u, n := leb128.DecodeUleb128([]byte{0xe5, 0x8e, 0x26, 'a', 'b', 'c'})
    fmt.Printf("%d %d\n", u, n) //=> 624485 3

// Decode signed LEB128, n is the number of bytes read
    s, n := leb128.DecodeSleb128([]byte{0x9b, 0xf1, 0x59, 'd', 'e', 'f'})
    fmt.Printf("%d %d\n", s, n) //=> -624485 3
}
```
