Module Container = Core_kernel.Container

Signature

include Core_kernel.Container_intf.Container
module type S0 = Container_intf.S0
module type S1 = Container_intf.S1

Generic definitions of container operations in terms of fold.

E.g.: iter ~fold t ~f = fold t ~init:() ~f:(fun () a -> f a).

type ('t, 'a, 'accum) fold = 't -> init:'accum -> f:('accum -> 'a -> 'accum) -> 'accum
type ('t, 'a) iter = 't -> f:('a -> unit) -> unit
val iter : fold:('t, 'a, unit) fold -> ('t, 'a) iter
val count : fold:('t, 'a, int) fold -> 't -> f:('a -> bool) -> int
val min_elt : fold:('t, 'a, 'a option) fold -> 't -> cmp:('a -> 'a -> int) -> 'a option
val max_elt : fold:('t, 'a, 'a option) fold -> 't -> cmp:('a -> 'a -> int) -> 'a option
val length : fold:('t, _, int) fold -> 't -> int
val to_list : fold:('t, 'a, 'a list) fold -> 't -> 'a list
val to_array : fold:('t, 'a, 'a list) fold -> 't -> 'a array
val sum : fold:('t, 'a, 'sum) fold -> (module Core_kernel.Commutative_group.S with type t = 'sum) -> 't -> f:('a -> 'sum) -> 'sum
val is_empty : iter:('t, 'a) iter -> 't -> bool

Generic definitions of container operations in terms of iter.

val exists : iter:('t, 'a) iter -> 't -> f:('a -> bool) -> bool
val for_all : iter:('t, 'a) iter -> 't -> f:('a -> bool) -> bool
val find : iter:('t, 'a) iter -> 't -> f:('a -> bool) -> 'a option
val find_map : iter:('t, 'a) iter -> 't -> f:('a -> 'b option) -> 'b option
module Make (T : Container_intf.Make_arg) : S1 with type 'a t := 'a T.t
The idiom for using Container.Make is to bind the resulting module and to explicitly import each of the functions that one wants:
module Make0 (T : Container_intf.Make0_arg) : S0 with type t := T.t and type elt := T.elt
