Description

Handling monad transformers.

Synopsis

runStateC :: (Data stateT, Monad m) => Cell (StateT stateT m) a b -> stateT -> Cell m a (b, stateT)
runStateC_ :: (Data stateT, Monad m) => Cell (StateT stateT m) a b -> stateT -> Cell m a b
data State stateT stateInternal = State {
- stateT :: stateT
- stateInternal :: stateInternal
}
runReaderC :: r -> Cell (ReaderT r m) a b -> Cell m a b
runReaderC' :: Monad m => Cell (ReaderT r m) a b -> Cell m (r, a) b

Documentation

runStateC Source #

Arguments

:: (Data stateT, Monad m)
=> Cell (StateT stateT m) a b	A cell with a state effect
-> stateT	The initial state
-> Cell m a (b, stateT)	The cell, returning its current state

Push effectful state into the internal state of a cell

runStateC_ Source #

Arguments

:: (Data stateT, Monad m)
=> Cell (StateT stateT m) a b	A cell with a state effect
-> stateT	The initial state
-> Cell m a b

Like runStateC, but does not return the current state.

data State stateT stateInternal Source #

The internal state of a cell to which runStateC or runStateL has been applied.
