Hy! Is there Any module in elixir which helps us in performing set operations?

  1. find Subset
  2. Find superset
  3. Find powerset etc

There is the MapSet module.

The MapSet.subset?/2 function can help you with the first 2 bulletpoints, though Iā€™m not quite sure what a powerset is.

As we are currently explaining in the slack to you, proposals that extend the standard library have to happen in the Core mailinglist.

Though due the ā€œcost of maintananceā€, it probably isnā€™t a proposal that would be accepted into the standard library and instead it would be better to create a library for your implementation and publish it on hex.

What would a function that generates a power set of a given set be useful for? The size of the output grows very rapidly, and checking "is this set X in P(S)" is easier to implement by checking that every element of X is in S.

I thought thatā€™s a fun exercise so I wrote a module for that:
