| Compression

|
| data CompressionLevel |
| Control amount of compression. This is a trade-off between the amount
of compression and the time and memory required to do the compression.
| | Constructors | | DefaultCompression | The default compression level is 6 (that is,
biased towards high compression at expense of speed).
| | NoCompression | No compression, just a block copy.
| | BestSpeed | The fastest compression method (less compression)
| | BestCompression | The slowest compression method (best compression).
| | CompressionLevel Int | A specific compression level between 1 and 9.
