Control.Monad.Par.Unsafe
Description
Unsafe operations. NOT part of "Safe Haskell".
These are "unsafe" (in the normal, Haskell sense) when used with a
"runPar" of type `Par a -> a`. If used with a runParIO that
stays in the IO monad, then they are simply dangerous.
For the purposes of Safe Haskell, any module that imports this module becomes untrustworthy.
- class ParUnsafe iv p | p -> iv where
- unsafePeek :: iv a -> p (Maybe a)
- unsafeTryPut :: iv a -> a -> p a
- unsafeParIO :: IO a -> p a
Documentation
class ParUnsafe iv p | p -> iv where
The class of Par monads that provide unsafe functionality.
Methods
unsafePeek :: iv a -> p (Maybe a)
Peek at the current contents of an IVar in a nonblocking way.
unsafeTryPut :: iv a -> a -> p a
Attempt to put a value into an IVar. If successful, return the
value put. If something is already there, return it instead.
unsafeParIO :: IO a -> p a
Lift an IO operation into the Par monad.
