Convenient functions to work with Reader monad
usingReader :: r -> Reader r a -> a Source #
Shorter and more readable alias for flip runReader.
usingReaderT :: r -> ReaderT r m a -> m a Source #
Shorter and more readable alias for flip runReaderT.
Convenient functions to work with State monad
evaluatingState :: s -> State s a -> a Source #
Alias for flip evalState. It's not shorter but sometimes
more readable. Done by analogy with using* functions family.
evaluatingStateT :: Functor f => s -> StateT s f a -> f a Source #
Alias for flip evalStateT. It's not shorter but sometimes
more readable. Done by analogy with using* functions family.
executingState :: s -> State s a -> s Source #
Alias for flip execState. It's not shorter but sometimes
more readable. Done by analogy with using* functions family.
executingStateT :: Functor f => s -> StateT s f a -> f s Source #
Alias for flip execStateT. It's not shorter but sometimes
more readable. Done by analogy with using* functions family.
usingState :: s -> State s a -> (a, s) Source #
Shorter and more readable alias for flip runState.
usingStateT :: s -> StateT s m a -> m (a, s) Source #
Shorter and more readable alias for flip runStateT.
