# Module BatMap.S.Labels

    module Labels: sig .. end

Operations on `Map` with labels.

This module overrides a number of functions of `Map` by functions in which some arguments require labels. These labels are there to improve readability and safety and to let you change the order of arguments to functions. In every case, the behavior of the function is identical to that of the corresponding function of `Map`.

    val add : key:BatMap.S.key -> data:'a -> 'a BatMap.S.t -> 'a BatMap.S.t

    val iter : f:(key:BatMap.S.key -> data:'a -> unit) -> 'a BatMap.S.t -> unit

    val map : f:('a -> 'b) -> 'a BatMap.S.t -> 'b BatMap.S.t

    val mapi : f:(key:BatMap.S.key -> data:'a -> 'b) -> 'a BatMap.S.t -> 'b BatMap.S.t

    val filterv : f:('a -> bool) -> 'a BatMap.S.t -> 'a BatMap.S.t

    val filter : f:(BatMap.S.key -> 'a -> bool) -> 'a BatMap.S.t -> 'a BatMap.S.t

    val fold : f:(key:BatMap.S.key -> data:'a -> 'b -> 'b) -> 'a BatMap.S.t -> init:'b -> 'b

    val compare : cmp:('a -> 'a -> int) -> 'a BatMap.S.t -> 'a BatMap.S.t -> int

    val equal : cmp:('a -> 'a -> bool) -> 'a BatMap.S.t -> 'a BatMap.S.t -> bool
