Hackage Build Status

Changes

1.1

  • Melded the API of foreign-var 0.1 with the API of StateVar 1.0.1.1
  • Introduced HasUpdate, which permits a wider array of uses of these combinators, including usecases that must update atomically.
  • Switched to multi-parameter typeclasses. This permits Ptr a to be directly employed as an instance of HasGetter, HasUpdate, and HasSetter.
