Types

type Gzip

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

Gzip is an interface to create Writer and Reader implementation.

func New

func New() Gzip

New returns Gzip implementation.

type MockGzip

type MockGzip struct {
	NewWriterLevelFunc func(w io.Writer, level int) (Writer, error)
	NewReaderFunc      func(r io.Reader) (Reader, error)
}

MockGzip represents mock struct of Gzip.

func (*MockGzip) NewReader

func (m *MockGzip) NewReader(r io.Reader) (Reader, error)

NewReader calls NewReaderFunc.

func (*MockGzip) NewWriterLevel
