type Compressor interface {
	Compress(w io.Writer, data []byte) (int, error)
	Decompress(reader io.ReadCloser) (io.ReadCloser, error)
}

Compressor abstracts the interface for a compression handler.

type Compressors struct {
	// contains filtered or unexported fields
}

func NewCompressors() *Compressors

NewCompressors create a Compressors instance.

func (c Compressors) AcceptEncoding() string

AcceptEncoding returns the Accept-Encoding header with supported compression encodings.

func (c Compressors) Compress(w io.Writer, encoding string, data []byte) (int, error)

Compress writes compressed data.

func (c Compressors) Decompress(reader io.ReadCloser, encoding string) (io.ReadCloser, error)

Decompress reads and decompresses the reader with equivalent the content encoding.

func (c Compressors) IsEncodingSupported(encoding string) bool

IsEncodingSupported checks if the input encoding is supported.

type DeflateCompressor struct{}

DeflateCompressor implements the compression handler for deflate encoding.

func (dc DeflateCompressor) Compress(w io.Writer, data []byte) (int, error)
