atomic-primops: A safe approach to CAS and other atomic ops in Haskell.
After GHC 7.4 a new casMutVar#
primop became available, but it's
difficult to use safely, because pointer equality is a highly
unstable property in Haskell. This library provides a safer method
based on the concept of Tickets.
.
Also, this library uses the "foreign primop" capability of GHC to
add access to other variants that may be of
interest, specifically, compare and swap inside an array.
.
Note that as of GHC 7.8, the relevant primops have been included in GHC itself.
This library is engineered to work pre- and post-GHC-7.8, while exposing the
same interface.
