Moduleprimitive-unlifted-2.1.0.0Haskell2010

Data.Primitive.Unlifted.MVar.ST

This module includes all the features of Control.Concurrent.MVar, except that the functions in Data.Primitive.Unlifted.Weak subsume the functionality of mkWeakMV and addMVarFinalizer, so we do not include analogues of those functions.
