Control-Monad-ST2: A variation on the ST monad with two type parameters.

[ bsd3, control, library ] [ Propose Tags ] [ Report a vulnerability ]

The ST2 monad is like the ST monad, but with finer-grained control over access to mutable state. The phantom type parameters r and w are used to track the read and write dependencies of the computation. If a computation of type ST2 r w a is polymorphic in w then it does not write any external state. If it is also polymorphic in r then it does not read any external state.

Readme for Control-Monad-ST2-0.1.0.1

[back to package description] 
Control.Monad.ST2
=================

The Control.Monad.ST2 monad is like the Control.Monad.ST monad, but
with finer-grained control over access to mutable state. The phantom
type parameters r and w are used to track the read and write
dependencies of the computation. If a computation of type ST2 r w a is
polymorphic in w then it does not write any external state. If it is
also polymorphic in r then it does not read any external state.
