type'at ='a list
val compare : ('a -> 'a -> int) -> 'a t -> 'a t -> intThe lexicographic order supported by the provided order. There is no constraint on the relative lengths of the lists.
val equal : ('a -> 'a -> bool) -> 'a t -> 'a t -> boolReturns true iff the given lists have the same length and content
with respect to the given equality function.
val filter_map : ('a -> 'b option) -> 'a t -> 'b tfilter_map f l applies f to every element of l, filters
out the None elements and returns the list of the arguments of
the Some elements.
val some_if_all_elements_are_some : 'a option t -> 'a t optionIf all elements of the given list are Some _ then Some xs
is returned with the xs being the contents of those Somes, with
order preserved. Otherwise return None.
val map2_prefix : ('a -> 'b -> 'c) ->
'a t ->
'b t -> 'c t * 'b tlet r1, r2 = map2_prefix f l1 l2
If l1 is of length n and l2 = h2 @ t2 with h2 of length n,
r1 is List.map2 f l1 h1 and r2 is t2.
val split_at : int -> 'a t -> 'a t * 'a tsplit_at n l returns the pair before, after where before is
the n first elements of l and after the remaining ones.
If l has less than n elements, raises Invalid_argument.
