DEPRECATED: use the "contravariant" package
|Latest on Hackage:||0.1.0.1|
This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
This library provides a
Cofunctor class useful for types
that are sinks or make use of IO effects. See documentation
Some supporting constructions are also provided.
