Documentation
class Shortcutable s where Source
class of things that can be run in parallel and can be shortcuted. The funtion in parameter is called everytime an intermediate result is known, as soon as it returns True the intermediate results are returned (discarding those not yet available). the order of the lists must be preserved
Instances
shortcut_ :: (Functor s, Shortcutable s) => [s a] -> ([a] -> Bool) -> s [a] Source
version without the maybes
shortcut2 :: (Functor s, Monad s, Shortcutable s) => [s a] -> [s b] -> ([Maybe a] -> [Maybe b] -> Bool) -> s ([Maybe a], [Maybe b]) Source
version with two different types of result
shortcut2b :: (Functor s, Monad s, Shortcutable s) => [s a] -> s b -> ([Maybe a] -> Bool -> Bool) -> s ([Maybe a], Bool) Source
version with a supplementary event which result is discarded
