Quickcheck generator for lists with additional customization.

List.gen' t produces a generator for arbitrary lists of values from t.

  • Adding ~length:(`Exactly n) produces only lists of length n.
  • Adding ~length:(`At_least n) produces only lists of length n or greater.
  • Adding ~length:(`At_most n) produces only lists of length n or less.
  • Adding ~length:(`Between_inclusive (m,n)) produces only lists of length k such that m <= k and k <= n.

The lists in the output of list t are generated uniquely, so long as the values in t are generated uniquely.

val gen_permutations : 'a t ‑> 'a t Core_kernel.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 stable_dedup : 'a list ‑> 'a list

stable_dedup Same as dedup but maintains the order of the list and doesn't allow compare function to be specified (otherwise, the implementation in terms of Set.t would hide a heavyweight functor instantiation at each call).
