README
monad-var
The aim of this library is to provide a unified set of operations (new
, read
, write
, swap
, various strict mutate*
functions and their derivatives (like mutate-and-return-the-old-value) and a certain interface for MVar
-like things) over all common variable types: IORef
, STRef s
, MVar
, TVar
, TMVar
.
When possible type classes are generalized to be over abstract containers rather than variables: e.g. it'd make sense to implement MonadRead TChan
and MonadMutate_ Vector
instances, but no such instances are provided right now.
There are also some lenses to be described in an upcoming blog post.
