Arguments
| :: MonadIO m | |
| => Int | Compression level |
| -> WindowBits | Zlib parameter (see the zlib-bindings package as well as the zlib C library) |
| -> Enumeratee ByteString ByteString m a |
Compress (deflate) a stream of ByteStrings. The WindowBits also control
the format (zlib vs. gzip).
Arguments
| :: MonadIO m | |
| => WindowBits | Zlib parameter (see the zlib-bindings package as well as the zlib C library) |
| -> Enumeratee ByteString ByteString m a |
Decompress (inflate) a stream of ByteStrings. For example:
run $ enumFile "test.z" $$ decompress defaultWindowBits $$ printChunks True
gzip :: MonadIO m => Enumeratee ByteString ByteString m aSource
Gzip compression with default parameters.
ungzip :: MonadIO m => Enumeratee ByteString ByteString m aSource
Gzip decompression with default parameters.

data ZlibException
Exception that can be thrown from the FFI code. The parameter is the numerical error code from the zlib library. Quoting the zlib.h file directly:
- #define Z_OK 0
- #define Z_STREAM_END 1
- #define Z_NEED_DICT 2
- #define Z_ERRNO (-1)
- #define Z_STREAM_ERROR (-2)
- #define Z_DATA_ERROR (-3)
