Functions

func Is

func Is(r io.Reader) (bool, error)

Is detects whether the input stream is compressed.

func ReadCloser

func ReadCloser(r io.ReadCloser) io.ReadCloser

ReadCloser reads uncompressed input data from the io.ReadCloser and returns an io.ReadCloser from which compressed data may be read. This uses gzip.BestSpeed for the compression level.

func ReadCloserLevel

func ReadCloserLevel(r io.ReadCloser, level int) io.ReadCloser

ReadCloserLevel reads uncompressed input data from the io.ReadCloser and returns an io.ReadCloser from which compressed data may be read. Refer to compress/gzip for the level: https://golang.org/pkg/compress/gzip/#pkg-constants

func UnzipReadCloser

func UnzipReadCloser(r io.ReadCloser) (io.ReadCloser, error)

UnzipReadCloser reads compressed input data from the io.ReadCloser and returns an io.ReadCloser from which uncompessed data may be read.
