Types

type Header

type Header = lz4.Header

Header is type alias of lz4.Header.

type LZ4

type LZ4 interface {
	NewWriterLevel(w io.Writer, level int) Writer
	NewWriter(w io.Writer) Writer
	NewReader(r io.Reader) Reader
}

LZ4 is an interface to create Writer and Reader implementation.

func New

func New() LZ4

New returns LZ4 implementation.

type MockLZ4

type MockLZ4 struct {
	NewWriterFunc      func(w io.Writer) Writer
