Foldable.S
The complete module signature for Foldable
for types with a single type variable.
val fold_left : f:('b -> 'a -> 'b) -> init:'b -> 'a t -> 'b
Left associative fold of a data structure; this is the same as the function derived from [@@deriving fold]
but with labelled arguments
val fold_right : f:('a -> 'b -> 'b) -> init:'b -> 'a t -> 'b
Right associative fold of a data structure
val any : pred:('a -> bool) -> ?init:bool -> 'a t -> bool
Test whether any element of the data structure satisfies the supplied predicate. The optional argument init
specifies the starting value and defaults to false
.
val all : pred:('a -> bool) -> ?init:bool -> 'a t -> bool
Test whether all elements of the the data structure satify the supplied predicate. The optional argument init
specifies the starting value and defaults to true
.
