Sourcemodule Key : sig ... end

Keys.

Maps

Sourcetype t

The type for heterogeneous value maps.

Sourceval empty : t

empty is the empty map.

Sourceval is_empty : t -> bool

is_empty m is true iff m is empty.

Sourceval mem : 'a key -> t -> bool

mem k m is true iff k is bound in m.

Sourceval add : 'a key -> 'a -> t -> t

add k v m is m with k bound to v.

Sourceval singleton : 'a key -> 'a -> t

singleton k v is add k v empty.

Sourceval rem : 'a key -> t -> t

rem k m is m with k unbound.

Sourceval find : 'a key -> t -> 'a option

find k m is the value of k's binding in m, if any.

Sourceval get : 'a key -> t -> 'a

get k m is the value of k's binding in m.

Sourcetype binding =
  1. | B : 'a key * 'a -> binding

The type for bindings.

Sourceval iter : (binding -> unit) -> t -> unit

iter f m applies f to all bindings of m.

Sourceval fold : (binding -> 'a -> 'a) -> t -> 'a -> 'a

fold f m acc folds over the bindings of m with f, starting with acc

Sourceval for_all : (binding -> bool) -> t -> bool

for_all p m is true iff all bindings of m satisfy p.

Sourceval exists : (binding -> bool) -> t -> bool

exists p m is true iff there exists a bindings of m that satisfies p.

Sourceval filter : (binding -> bool) -> t -> t

filter p m are the bindings of m that satisfy p.

Sourceval cardinal : t -> int

cardinal m is the number of bindings in m.

Sourceval any_binding : t -> binding option

any_binding m is a binding of m (if not empty).

Sourceval get_any_binding : t -> binding

get_any_binding m is a binding of m.
