go-lz4 is port of LZ4 lossless compression algorithm to Go. The original C code is located at:
go get github.com/bkaradzic/go-lz4 import "github.com/bkaradzic/go-lz4"
The package name is
- go-lz4 saves a uint32 with the original uncompressed length at the beginning of the encoded buffer. They may get in the way of interoperability with other implementations.

func CompressBound ¶
CompressBound returns the maximum length of a lz4 block, given it's uncompressed length
Decode returns the decoded form of src. The returned slice may be a subslice of dst if it was large enough to hold the entire decoded block.
