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.

Checks whether the provided element is there, using equal
.

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

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 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_array : ('a, _) t ‑> 'a array
val min_elt : ('a, _) t ‑> cmp:('a ‑> 'a ‑> int) ‑> 'a option
Returns a min (resp max) element from the collection using the provided cmp
function. 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
. Returns None
iff the collection is empty.
