chan-split: Concurrent Chans as read/write pairs. Also provides generic Chan, Cofunctor classes.
A wrapper around Control.Concurrent.Chan that splits a Chan into a pair, one of which allows only read operations, the other write operations.
This makes code easier to reason about, allows us to define
useful instances (Functor
and Cofunctor
) on the chan
pairs.
In addition this package provides a module that defines a
pair of classes ReadableChan
and WritableChan
which
defines the basic methods any Chan type should provide.
To use standard Chans with these polymorphic functions, import as follows:
import Control.Concurrent.Chan hiding (readChan,writeChan,writeList2Chan) import Control.Concurrent.Chan.Class
When used alongside standard Chans, the Split module can be imported qualified like:
import qualified Control.Concurrent.Chan.Split as S
Note, we do not implement the deprecated unGetChan and isEmptyChan functions.
This module is used internally by the "simple-actors" package.
CHANGES:

to its own module "cofunctor"
- redefine chan pair classes using fundeps
to express the relationship between input
and output halfs of a Chan
- define NewSplitChan
class for chan pairs that can be
instantiated
