conduit-0.2.2: Streaming data processing library.
Conduits are an approach to the streaming data problem. It is meant as an alternative to enumerators/iterators, hoping to address the same issues with different trade-offs based on real-world experience with enumerators. For more information, see http://www.yesodweb.com/book/conduit.
Release history:
- 0.2
- Instead of storing state in mutable variables, we now use CPS. A
Source
returns the nextSource
, and likewise forSink
s andConduit
s. Not only does this take better advantage of GHC's optimizations (about a 20% speedup), but it allows some operations to have a reduction in algorithmic complexity from exponential to linear. This also allowed us to remove thePrepared
set of types. Also, theState
functions (e.g.,sinkState
) use better constructors for return types, avoiding the need for a dummy state on completion. - 0.1
-
BufferedSource
is now an abstract type, and has a much more efficient internal representation. The result was a 41% speedup on microbenchmarks (note: do not expect speedups anywhere near that in real usage). In general, we are moving towardsBufferedSource
being a specific tool used internally as needed, but usingSource
for all external APIs. - 0.0
- Initial release.
