type 'a t
val mem : 'a t ‑> 'a ‑> equal:('a ‑> 'a ‑> bool) ‑> bool

Checks whether the provided element is there, using equal.

val length : 'a t ‑> int
val is_empty : 'a t ‑> bool
val iter : 'a t ‑> f:('a ‑> unit) ‑> unit
val fold : 'a t ‑> init:'accum ‑> f:('accum ‑> 'a ‑> 'accum) ‑> 'accum

fold t ~init ~f returns f (... f (f (f init e1) e2) e3 ...) en, where e1..en are the elements of t

val fold_result : 'a t ‑> init:'accum ‑> f:('accum ‑> 'a ‑> ('accum, 'e) Base.Result.t) ‑> ('accum, 'e) Base.Result.t

fold_result t ~init ~f is a short-circuiting version of fold that runs in the Result monad. If f returns an Error _, that value is returned without any additional invocations of f.

val fold_until : 'a t ‑> init:'accum ‑> f:('accum ‑> 'a ‑> ('accum, 'stop) Base.Container_intf.Continue_or_stop.t) ‑> ('accum, 'stop) Base.Container_intf.Finished_or_stopped_early.t

fold_until t ~init ~f is a short-circuiting version of fold. If f returns Stop _ the computation ceases and results in that value. If f returns Continue _, the fold will proceed.

val exists : 'a t ‑> f:('a ‑> bool) ‑> bool

Returns true if and only if there exists an element for which the provided function evaluates to true. This is a short-circuiting operation.

val for_all : 'a t ‑> f:('a ‑> bool) ‑> bool

Returns true if and only if the provided function evaluates to true for all elements. This is a short-circuiting operation.

val count : 'a t ‑> f:('a ‑> bool) ‑> int

Returns the number of elements for which the provided function evaluates to true.

val sum : (module Base.Commutative_group.S with type t = 'sum) ‑> 'a t ‑> f:('a ‑> 'sum) ‑> 'sum

Returns the sum of f i for all i in the container.

val find : 'a t ‑> f:('a ‑> bool) ‑> 'a option

Returns as an option the first element for which f evaluates to true.

val find_map : 'a t ‑> f:('a ‑> 'b option) ‑> 'b option

Returns the first evaluation of f that returns Some, and returns None if there is no such element.

val to_list : 'a t ‑> 'a list
val to_array : 'a t ‑> 'a array
val min_elt : 'a t ‑> cmp:('a ‑> 'a ‑> int) ‑> 'a option

Returns a minimum (resp maximum) element from the collection using the provided cmp function, or None if the collection is empty. In case of a tie, the first element encountered while traversing the collection is returned. The implementation uses fold so it has the same complexity as fold.
