Module Bytesrw_zlib.Zlib

decompress_reads () r filters the reads of r by decompressing a zlib stream. If leftover is:

• false (default), the reader errors if there is leftover data after the end of the zlib stream.
• true the reader decompresses one zlib stream. Once the reader returns Bytes.Slice.eod, r is positioned exactly after the end of the zlib stream and can be read again to perform other non-filtered reads.

decompress_writes () w filters writes on w by decompressing a zlib stream until Bytes.Slice.eod is written, if leftover data remains an error is raised. The last Bytes.Slice.eod is not written on w and at this point w can be used again to perform other non-filtered writes.

compress_reads ~level () r filters the reads of r by compressing them to a zlib stream at level level (defaults to default_compression).

compress_writes ~level () w filters writes on w by compressing them to a zlib stream at level level (defaults to default_compression) until Bytes.Slice.eod is written. The latter is not written on w and at that point w can be used again to perform non-compressed writes.
