Module Using_comparator.Tree

type ('a, 'cmp) t

A Tree.t contains just the tree data structure that a set is based on, without including the comparator. Accordingly, any operation on a Tree.t must also take as an argument the corresponding comparator.

val length : (_, _) t -> int
val is_empty : (_, _) 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) Result.t) -> ('accum, 'e) 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 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__Container_intf.Summable 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.
