val fold_result : 'a t ‑> init:'accum ‑> f:('accum ‑> 'a ‑> ('accum, 'e) Base.Result.t) ‑> ('accum, 'e) Base.Result.tfold_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, 'final) Base__.Container_intf.Continue_or_stop.t) ‑> finish:('accum ‑> 'final) ‑> 'finalfold_until t ~init ~f ~finish 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. If f never returns Stop _, the final result
is computed by finish.
val exists : 'a t ‑> f:('a ‑> bool) ‑> boolReturns 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) ‑> boolReturns 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) ‑> intReturns 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) ‑> 'sumReturns the sum of f i for all i in the container.
val find : 'a t ‑> f:('a ‑> bool) ‑> 'a optionReturns as an option the first element for which f evaluates to true.
val find_map : 'a t ‑> f:('a ‑> 'b option) ‑> 'b optionReturns the first evaluation of f that returns Some, and returns None if there
is no such element.
val to_list : 'a t ‑> 'a listval to_array : 'a t ‑> 'a arrayval min_elt : 'a t ‑> compare:('a ‑> 'a ‑> int) ‑> 'a optionReturns a minimum (resp maximum) element from the collection using the provided
compare 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.
val max_elt : 'a t ‑> compare:('a ‑> 'a ‑> int) ‑> 'a optionThese are all like their equivalents in Container except that an index starting at
0 is added as the first argument to f.
