Description
This module exports utilities to compress and decompress GZip pipes
streams.

Streams
Arguments
| :: MonadIO m | |
| => Proxy x' x () ByteString m r | Compressed stream |
| -> Proxy x' x () ByteString m r | Decompressed stream |
Decompress bytes flowing from a Producer.

Decompress bytes flowing from a Producer, returning any leftover input
that follows the compressed stream.
Arguments
| :: MonadIO m | |
| => CompressionLevel | |
| -> Proxy x' x () ByteString m r | Decompressed stream |
| -> Proxy x' x () ByteString m r | Compressed stream |
Compress bytes flowing from a Producer.
