stm-chans
This package offers a collection of channel types, similar to
Control.Concurrent.STM.{TChan,TQueue} but with additional features.
In particular we offer the following data types:
Control.Concurrent.STM.TBChan: Bounded FIFO channels. When the channel is full, writers will block/retry. This ensures that the writers do not get too far ahead of the readers, which helps to make sure that memory and cpu resources are used responsibly.Control.Concurrent.STM.TMChan: Closeable FIFO channels.Control.Concurrent.STM.TMQueue: Closeable FIFO queues. LikeTChan (Maybe a)but with a monotonicity guarantee that onceNothingis returned all future reads will beNothingas well.Control.Concurrent.STM.TBMChan: Bounded Closeable FIFO channels.Control.Concurrent.STM.TBMQueue: Bounded Closeable FIFO queues. Combines the capabilities ofTBChanandTMChan.
Install
In general, this is a simple package and should be easy to install. It does require GHC however, because it relies on the Control.Concurrent.STM.TChan type which (for some unknown reason) is GHC-only. With the cabal-install program you can just do:
$> cabal install stm-chans
