                    archive(data:)

Archives data into GZip archive. Data will be also compressed with DEFLTATE algorithm. Fields in the header of the resulting archive will be set to default values (i.e. no mtime, no flags, no file name, unknown OS type). It will be also specified that the compressor used slowest DEFLATE algorithm.

If during compression something goes wrong DeflateError will be thrown.
