Task

Basics

succeed : a -> Task x a

fail : x -> Task x a

Mapping

map : (a -> b) -> Task x a -> Task x b

map2 : (a -> b -> result) -> Task x a -> Task x b -> Task x result

map3 : (a -> b -> c -> result) -> Task x a -> Task x b -> Task x c -> Task x result

(a -> b -> c -> d -> result)

-> Task x a

-> Task x b

-> Task x c

-> Task x d

-> Task x result

(a -> b -> c -> d -> e -> result)

-> Task x a

-> Task x b

-> Task x c

-> Task x d

-> Task x e

-> Task x result

andMap : Task x (a -> b) -> Task x a -> Task x b

Chaining

andThen : Task x a -> (a -> Task x b) -> Task x b

sequence : List (Task x a) -> Task x (List a)

Errors

onError : Task x a -> (x -> Task y a) -> Task y a

mapError : (x -> y) -> Task x a -> Task y a

toMaybe : Task x a -> Task y (Maybe a)

fromMaybe : x -> Maybe a -> Task x a

toResult : Task x a -> Task y (Result x a)

fromResult : Result x a -> Task x a

Threads

spawn : Task x a -> Task y ThreadID

sleep : Time -> Task x ()
