.gunzip(src) ⇒ String

Decode the given gzipped +string+.

This method is almost equivalent to the following code:

def gunzip(string) sio = StringIO.new(string) gz = Zstdlib::GzipReader.new(sio, encoding: Encoding::ASCII_8BIT) gz.read ensure gz&.close end

See also Zstdlib.gzip

Returns:

  • (String)
