This package provides a pure interface for compressing and decompressing streams of data represented as lazy ByteStrings. It uses the zlib C library so it has high performance. It supports the "zlib", "gzip" and "raw" compression formats.

It provides a convenient high level API suitable for most tasks and for the few cases where more control is needed it provides access to the full zlib feature set.

Flags

Manual Flags

Name	Description	Default
non-blocking-ffi	The (de)compression calls can sometimes take a long time, which prevents other Haskell threads running. Enabling this flag avoids this unfairness, but with greater overall cost.	Enabled
bundled-c-zlib	Use zlib-clib package with C sources instead of a system library. C sources are used for GHCJS and WASM unconditionally and on Windows unless pkg-config flag is on.	Disabled

Automatic Flags

Name	Description	Default
pkg-config	Use pkg-config executable to locate foreign zlib library.	Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
