Sourcetype base_u

Raw unbounded type

Sourcetype u

base_u after bounding constraints have been applied

Sourcetype t = private u

Private version of u to avoid construction of t values without using make below.

Sourceval bounds : base_u bound_t * base_u bound_t

bounds defines the (min, max) bounds for the bounded range

Sourceval make : base_u -> t

make x will return a value of type t derived from x.

Sourceval extract : t -> u

extract x will return x as a value of type u. A similar result could be achieved with (x :> u)

Sourceval map : (base_u -> base_u) -> t -> t option

map f x applies f to x. Returns Some y if x can be converted back to type base_u, otherwise returns None.

Sourceval map2 : (base_u -> base_u -> base_u) -> t -> t -> t option

map2 f x y applies f to x and y. Returns Some z if x and y can be converted back to type base_u, otherwise returns None.

Sourceval map_exn : (base_u -> base_u) -> t -> t

map_exn f x applies f to x. Returns y if x can be converted back to type base_u, otherwise raise an exception.

Sourceval map2_exn : (base_u -> base_u -> base_u) -> t -> t -> t

map2_exn f x y applies f to x and y. Returns z if x and y can be converted back to type base_u, otherwise raise an exception.
