Control.Monad.Par.Unsafe

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.

classclass ParUnsafe (iv :: Type -> Type) (p :: Type -> Type) | 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.
