type 'a t

The type of the monad containing values of type 'a

val return : 'a -> 'a t

return a makes a monadic container containing the value a.

val (>>=) : 'a t -> ( 'a -> 'b t ) -> 'b t

m >>= f extracts the value a from the monadic container m and returns f a.

val (>=>) : ( 'a -> 'b t ) -> ( 'b -> 'c t ) -> 'a -> 'c t

f >=> g composition of the two monadic functions f and g.

f >=> g is equivalent to fun a -> f a >>= g.

val map : ( 'a -> 'b ) -> 'a t -> 'b t

map f m maps the values in the monadic container m with the function f.

val join : 'a t t -> 'a t

Remove one level of container. join m is equivalent to mm >>= fun m -> m.

val (<*>) : ( 'a -> 'b ) t -> 'a t -> 'b t

f <*> m applies the function contained in f to the content of the monadic container m and injects the result into a new monadic container.
