1. casUnliftedMutVar# :: forall s (a :: UnliftedType) . UnliftedMutVar# s a -> a -> a -> State# s -> (# State# s, Int#, a #)

   primitive-unlifted	Data.Primitive.Unlifted.MutVar.Primops

   Performs a machine-level compare and swap (CAS) operation on an UnliftedMutVar#. Returns a tuple containing an Int# which is '1#' when a swap is performed, along with the most "current" value from the UnliftedMutVar#. This return value can be used as the expected value if a CAS loop is required, though it may be better to get a fresh read. Note that this behavior differs from the more common CAS behavior, which is to return the old value before the CAS occured.

2. newUnliftedMutVar# :: forall (a :: UnliftedType) s . a -> State# s -> (# State# s, UnliftedMutVar# s a #)

   primitive-unlifted	Data.Primitive.Unlifted.MutVar.Primops

   No documentation available.

3. readUnliftedMutVar# :: forall s (a :: UnliftedType) . UnliftedMutVar# s a -> State# s -> (# State# s, a #)

   primitive-unlifted	Data.Primitive.Unlifted.MutVar.Primops

   No documentation available.

4. sameUnliftedMutVar# :: forall s (a :: UnliftedType) . UnliftedMutVar# s a -> UnliftedMutVar# s a -> Int#

   primitive-unlifted	Data.Primitive.Unlifted.MutVar.Primops

   Check whether two UnliftedMutVar#es refer to the same mutable variable. This is a check on object identity, and not on contents.

5. writeUnliftedMutVar# :: forall s (a :: UnliftedType) . UnliftedMutVar# s a -> a -> State# s -> State# s
