Putting data results in writing the compressed/decompressed output into a RingBuffer. You can retrieve the content of the RingBuffer via get_data. Support both gzip and deflate.

Stream peer handling GZIP and deflate compression/decompresison.

This class allows to compress or decompress data using GZIP/deflate in a streaming fashion. This is particularly useful when compressing or decompressing files that has to be sent through the network without having to allocate them all in memory.
|
|
After starting the stream via [method start_compression] (or [method start_decompression]), calling [method StreamPeer.put_partial_data] on this stream will compress (or decompress) the data, writing it to the internal buffer. Calling [method StreamPeer.get_available_bytes] will return the pending bytes in the internal buffer, and [method StreamPeer.get_partial_data] will retrieve the compressed (or decompressed) bytes from it. When the stream is over, you must call [method finish] to ensure the internal buffer is properly flushed (make sure to call [method StreamPeer.get_available_bytes] on last time to check if more data needs to be read after that).
