- evaluate :: a -> IO a
- isInterrupt :: AnException -> Bool
- discard :: a
- isDiscard :: AnException -> Bool
- finally :: IO a -> IO b -> IO a

type AnException = SomeException Source #
tryEvaluate :: a -> IO (Either AnException a) Source #
tryEvaluateIO :: IO a -> IO (Either AnException a) Source #
isInterrupt :: AnException -> Bool Source #
Test if an exception was a ^C.
QuickCheck won't try to shrink an interrupted test case.
A special exception that makes QuickCheck discard the test case.
Normally you should use ==>, but if for some reason this isn't
possible (e.g. you are deep inside a generator), use discard
instead.
isDiscard :: AnException -> Bool Source #
