Class type

A Balanced_reducer.t stores a mutable fixed-length sequence of optional values, and incrementally maintains the result of folding an associative operation (reduce) over the sequence as its elements change.

type 'a t
val sexp_of_t : ('a -> Sexplib0.Sexp.t) -> 'a t -> Sexplib0.Sexp.t
include Base.Invariant.S1 with type 'a t := 'a t
val invariant : ('a -> unit) -> 'a t -> unit
val create_exn : ?sexp_of_a:('a -> Base.Sexp.t) -> Base.unit -> len:Base.int -> reduce:('a -> 'a -> 'a) -> 'a t

create_exn ~len ~reduce creates a balanced reducer of length len, all of whose elements are None. It raises if len < 1.

val set_exn : 'a t -> Base.int -> 'a -> Base.unit

set_exn t i a updates the value at index i to Some a. It raises if i is out of bounds.

val get_exn : 'a t -> Base.int -> 'a

get_exn t i gets the value at index i. It raises if i is out of bounds, or set_exn t i has never been called.

val compute_exn : 'a t -> 'a

compute_exn t computes the value of the fold. It raises if any values of the array are None.
