go-lz4

go-lz4 is port of LZ4 lossless compression algorithm to Go.The original C code is located at:

https://code.google.com/p/lz4/

Usage

go get github.com/bkaradzic/go-lz4

import "github.com/bkaradzic/go-lz4"

The package name is lz4

Notes

There are two difference between original implementation and Go version:

  • Data is encoded and decoded as a stream. There is no size argument requirement.

  • go-lz4 doesn't save magic value and chunk size at the begining of the file. Due this difference file produced by original lz4 implementation can't be decompressed by go-lz4 implementation without ignoring first 8 bytes of file.
