Dialyzer error

[bradleygolden]

After the latest version bump to 2.0.0, for some reason including Burnex.is_burner?/1 in my application results in the following dialyzer error:

The guard test:

/=(_ :: false, false)

can never succeed.

I'm fairly confident that it's the is_burner/1 function as the second I remove the error goes away. Any thoughts on what's causing this?

Hi @bradleygolden, sorry about this issue. I indeed saw some warnings with Dialyzer after we turned providers into a MapSet that seemed related with https://elixirforum.com/t/dialyzer-complaint-about-mapset-member-not-getting-proper-type-as-argument-possible-specs-bug-in-mapset/20780/15.

I didn't have much time to investigate so I just added a @dialyzer ignore, but I didn't think it would impact dependant projects.

I can't look at that right now, but happy to merge any contribution to fix this. We can also remove Dialyzer from this project if it simplifies things - the value added for such a small library is arguably low.

I had some difficulty finding a good fix for this other than maybe doing something hacky. I think for now I'm just going to ignore the dialyzer error and call it a day.

Do you think it's possible dialyzer will still throw an error in dependent projects if you remove it from this project? This might be worth double checking just to be safe.
