Documentation
errorWithoutStackTrace :: forall (r :: RuntimeRep) (a :: TYPE r). [Char] -> a #
A variant of error that does not produce a stack trace.
Since: base-4.9.0.0
fromLeft :: a -> Either a b -> a #
Return the contents of a Left-value or a default value otherwise.
Examples
Basic usage:
>>>fromLeft 1 (Left 3)3>>>fromLeft 1 (Right "foo")1
Since: base-4.10.0.0
fromRight :: b -> Either a b -> b #
Return the contents of a Right-value or a default value otherwise.
Examples
Basic usage:
>>>fromRight 1 (Right 3)3>>>fromRight 1 (Left "foo")1
Since: base-4.10.0.0
unsafeWithForeignPtr :: ForeignPtr a -> (Ptr a -> IO b) -> IO b Source #
