Extensions

val stable_dedup_staged : compare:('a -> 'a -> Base.Int.t) -> ('a Base.List.t -> 'a Base.List.t) Core__.Import.Staged.t

stable_dedup_staged is the same as dedup_and_sort but maintains the order of the list. This function is staged because it instantiates a functor when compare is passed.

See also Set.stable_dedup_list, which is the underlying implementation of this function and lets you avoid the functor instantiation when you already have such a module on hand.

exception Duplicate_found of Base.Unit.t -> Base.Sexp.t * Base.String.t

Only raised in exn_if_dup below.

  • deprecated [since 2018-03] stop matching on Duplicate_found. [exn_if_dup] will eventually raise a different and unspecified exception
val exn_if_dup : compare:('a -> 'a -> Base.Int.t) -> ?context:Base.String.t -> 'a t -> to_sexp:('a -> Base.Sexp.t) -> Base.Unit.t

exn_if_dup ~compare ?context t ~to_sexp raises if t contains a duplicate. It will specifically raise a Duplicate_found exception and use context as its second argument. O(n log n) time complexity.

val slice : 'a t -> Base.Int.t -> Base.Int.t -> 'a t

slice t start stop returns a new list including elements t.(start) through t.(stop-1), normalized Python-style with the exception that stop = 0 is treated as stop = length t.

include Comparator.Derived with type 'a t := 'a t
type !'cmp comparator_witness
val comparator : ('a, 'cmp) Comparator.comparator -> ('a t, 'cmp comparator_witness) Comparator.comparator
include Quickcheckable.S1 with type 'a t := 'a t
val quickcheck_generator : 'a Base_quickcheck.Generator.t -> 'a t Base_quickcheck.Generator.t
val quickcheck_observer : 'a Base_quickcheck.Observer.t -> 'a t Base_quickcheck.Observer.t
val quickcheck_shrinker : 'a Base_quickcheck.Shrinker.t -> 'a t Base_quickcheck.Shrinker.t
val to_string : f:('a -> Base.String.t) -> 'a t -> Base.String.t
val gen_non_empty : 'a Quickcheck.Generator.t -> 'a t Quickcheck.Generator.t

Like gen, but never generates the empty list.

val gen_with_length : Base.Int.t -> 'a Quickcheck.Generator.t -> 'a t Quickcheck.Generator.t

Like gen, but generates lists with the given length.

val gen_filtered : 'a t -> 'a t Quickcheck.Generator.t

Randomly drops elements from the input list. Length is chosen uniformly between 0 and the length of the input, inclusive.

val gen_permutations : 'a t -> 'a t Quickcheck.Generator.t

gen_permutations t generates all permutations of list. If t contains duplicate values, then gen_permutations t will produce duplicate lists.

val zip_with_remainder : 'a Base.List.t -> 'b Base.List.t -> ('a * 'b) Base.List.t * ('a Base.List.t, 'b Base.List.t) Either.t Base.Option.t

zip_with_remainder xs ys zips as many elements as possible of xs and ys together and also returns the un-zipped remainder of the longer input, if the inputs have different lengths.

If xs and ys have the same length, zip_with_remainder xs ys returns the same thing as (zip_exn xs ys, None)
