Returns a Pipe that deflates (compresses) its input elements using a java.util.zip.Deflater with the parameters level, nowrap and strategy.

Returns a pipe that incrementally decompresses input according to the GZIP format. Any errors in decompression will be sequenced as exceptions into the output stream. The implementation of this pipe delegates directly to GZIPInputStream. Despite this, decompression is still handled in a streaming and async fashion without any thread blockage. Under the surface, this is handled by enqueueing chunks into a special type of byte array InputStream which throws exceptions when exhausted rather than blocking. These signal exceptions are caught by the pipe and treated as an async suspension. Thus, there are no issues with arbitrarily-framed data and chunk boundaries. Also note that there is almost no performance impact from these exceptions, due to the way that the JVM handles throw/catch.

The chunk size here is actually really important. If you set it to be too small, then there will be insufficient buffer space for GZIPInputStream to read the GZIP header preamble. This can result in repeated, non-progressing async suspensions. This case is caught internally and will be raised as an exception (NonProgressiveDecompressionException) within the output stream. Under normal circumstances, you shouldn't have to worry about this. Just, uh, don't set the buffer size to something tiny. Matching the input stream largest chunk size, or roughly 8 KB (whichever is larger) is a good rule of thumb.

Returns a pipe that incrementally compresses input into the GZIP format by delegating to java.util.zip.GZIPOutputStream. Output is compatible with the GNU utils gunzip utility, as well as really anything else that understands GZIP. Note, however, that the GZIP format is not "stable" in the sense that all compressors will produce identical output given identical input. Part of the header seeding is arbitrary and chosen by the compression implementation. For this reason, the exact bytes produced by this pipe will differ in insignificant ways from the exact bytes produced by a tool like the GNU utils gzip.

Returns a Pipe that inflates (decompresses) its input elements using a java.util.zip.Inflater with the parameter nowrap.
