Module CCIntMapSource

Map specialized for Int keys

status: stable

Sourcetype +'a t
Sourceval empty : 'a t
Sourceval is_empty : _ t -> bool

Is the map empty?

Sourceval singleton : int -> 'a -> 'a t
Sourceval doubleton : int -> 'a -> int -> 'a -> 'a t
Sourceval mem : int -> _ t -> bool
Sourceval find : int -> 'a t -> 'a option
Sourceval find_exn : int -> 'a t -> 'a

Same as find but unsafe.

Sourceval add : int -> 'a -> 'a t -> 'a t
Sourceval remove : int -> 'a t -> 'a t
Sourceval equal : eq:('a -> 'a -> bool) -> 'a t -> 'a t -> bool

equal ~eq a b checks whether a and b have the same set of pairs (key, value), comparing values with eq.

Sourceval compare : cmp:('a -> 'a -> int) -> 'a t -> 'a t -> int

Total order between maps; the precise order is unspecified.

Sourceval update : int -> ('a option -> 'a option) -> 'a t -> 'a t
Sourceval filter : (int -> 'a -> bool) -> 'a t -> 'a t

Filter values using the given predicate

  • since 2.3
Sourceval filter_map : (int -> 'a -> 'b option) -> 'a t -> 'b t

Filter-map values using the given function

  • since 2.3
Sourceval cardinal : _ t -> int

Number of bindings in the map. Linear time.

Sourceval iter : (int -> 'a -> unit) -> 'a t -> unit
Sourceval fold : (int -> 'a -> 'b -> 'b) -> 'a t -> 'b -> 'b
Sourceval mapi : (int -> 'a -> 'b) -> 'a t -> 'b t

Sourceval choose : 'a t -> (int * 'a) option
Sourceval choose_exn : 'a t -> int * 'a
Sourceval union : (int -> 'a -> 'a -> 'a) -> 'a t -> 'a t -> 'a t
Sourceval inter : (int -> 'a -> 'a -> 'a) -> 'a t -> 'a t -> 'a t
Sourceval merge : f:(int -> [ `Left of 'a | `Right of 'b | `Both of 'a * 'b ] -> 'c option) -> 'a t -> 'b t -> 'c t

merge ~f m1 m2 merges m1 and m2 together, calling f once on every key that occurs in at least one of m1 and m2. if f k binding = Some c then k -> c is part of the result, else k is not part of the result.
