I am generating a list of atoms which looks like this,
[:c, :u, :d]
|> StreamData.one_of()
|> StreamData.list_of()
…
A little more logic to it, but it generates this:
[[:c], [:c, :c, :u], [:c, :u, :u, :c], [:c], [:c, :d, :c], [:c, :c, :d],
[:c, :d, :c, :u, :d, :c, :d], [:c, :d, :c, :u], [:c, :d, :c],
[:c, :c, :u, :d, :d, :c, :u, :u, :u, :c, :d], [:c, :c, :c], …
Any way to ensure no dupes are generated?
Suspect the best way is with Enum?
E.g. [:c] is closely followed by [:c].
Not a big deal, just wondering, if it can be done in StreamData itself..
Where Next?

Nothing prevents you from making a generator that produces one such atom list and then compose it through
uniq_list_ofon a higher level. Unless I misunderstood you.mmport80
I thought so also, but afaict, it ensures the elements of each individual list are unique, i.e. not
[:a, :a]Rather than not
[[:a, :b], [:a, :b]]sneako
Maybe
uniq_list_of/2is what you are looking for? StreamData — StreamData v1.3.0
