putForceTMVar :: TMVar a -> a -> STM ()

newtype TMapMVar k a

Constructors

TMapMVar

Fields

getTMapMVar :: TVar (Map k (TMVar a))

newTMapMVar :: STM (TMapMVar k a)

keys :: TMapMVar k a -> STM [k]

peekElems :: TMapMVar k a -> STM [a]

insert :: Ord k => TMapMVar k a -> k -> a -> IO ()

Blocks if it's full

insertForce :: Ord k => TMapMVar k a -> k -> a -> IO ()

Doesn't Block

lookup :: Ord k => TMapMVar k a -> k -> IO a

Blocks, and deletes upon looking it up

tryLookup :: Ord k => TMapMVar k a -> k -> IO (Maybe a)

observe :: Ord k => TMapMVar k a -> k -> IO a

Blocks, but doesn't delete when looking it up

tryObserve :: Ord k => TMapMVar k a -> k -> IO (Maybe a)

delete :: Ord k => TMapMVar k a -> k -> IO ()

Utils

getTMVar :: Ord k => TMapMVar k a -> k -> IO (TMVar a)
