val union : 'a t -> 'a t -> f:(key -> 'a -> 'a -> 'a option) -> 'a t
val union_exn : 'a t -> 'a t -> 'a t

Like union but raises a code error if a key appears in both maps.

val superpose : 'a t -> 'a t -> 'a t

superpose a b is b augmented with bindings of a that are not in b.

val of_list_unit : key list -> unit t
val of_list_fold : (key * 'a) list -> init:'b -> f:('b -> 'a -> 'b) -> 'b t

Return a map of (k, v) bindings such that:

v = f init @@ f v1 @@ fv2 @@ ... @@ f vn

where v1, v2, ... vn are the values associated to k in the input list, in the order in which they appear. This is essentially a more efficient version of:

of_list_multi l |> map ~f:(List.fold_left ~init ~f)
val keys : 'a t -> key list
val values : 'a t -> 'a list
val min_binding : 'a t -> (key * 'a) option
val max_binding : 'a t -> (key * 'a) option
val choose : 'a t -> (key * 'a) option
val split : 'a t -> key -> 'a t * 'a option * 'a t
val find : 'a t -> key -> 'a option
val find_exn : 'a t -> key -> 'a
val find_key : 'a t -> f:(key -> bool) -> key option
val map : 'a t -> f:('a -> 'b) -> 'b t
val mapi : 'a t -> f:(key -> 'a -> 'b) -> 'b t
val fold_mapi : 'a t -> init:'acc -> f:(key -> 'acc -> 'a -> 'acc * 'b) -> 'acc * 'b t
val filter_map : 'a t -> f:('a -> 'b option) -> 'b t
val filter_mapi : 'a t -> f:(key -> 'a -> 'b option) -> 'b t
val filter_opt : 'a option t -> 'a t
val is_subset : 'a t -> of_:'b t -> f:('a -> of_:'b -> bool) -> bool

is_subset t ~of_ ~f is true iff all keys in t are in of_ and f is true for all keys that are in both.
