Constructors

TMapMVar

Fields

• getTMapMVar :: TVar (HashMap k (TMVar a))

newTMapMVar :: STM (TMapMVar k a)

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

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

insert :: (Eq k, Hashable k) => TMapMVar k a -> k -> a -> STM ()

Blocks if it's full

insertForce :: (Eq k, Hashable k) => TMapMVar k a -> k -> a -> STM ()

Doesn't Block

lookup :: (Eq k, Hashable k) => TMapMVar k a -> k -> STM a

Blocks, and deletes upon looking it up

tryLookup :: (Eq k, Hashable k) => TMapMVar k a -> k -> STM (Maybe a)

observe :: (Eq k, Hashable k) => TMapMVar k a -> k -> STM a

Blocks, but doesn't delete when looking it up

tryObserve :: (Eq k, Hashable k) => TMapMVar k a -> k -> STM (Maybe a)

delete :: (Eq k, Hashable k) => TMapMVar k a -> k -> STM ()

Utils

getTMVar :: (Eq k, Hashable k) => TMapMVar k a -> k -> STM (TMVar a)
