To explain

There are 2 Error struct / enum declarations, probably in separate files

To the ?, they are different types and cannot be converted from one to the other (because they are two disparate structs that happen to have the same name, but can have different bodies)

To fix this

You can either use .some_func_result().map_err(|err| /* conversion here/*)?; +

Or you can impl From<Error1> for Error2

And you should also name it ThingError, so you can visually differentiate the two

+ There are like 10 different mapping functions, depending on if you’re using an option or a result

I never remember which one specifically i need, (unwrap_or, map_or, map_or_else, ok, ok_or)

I usually just hunt through the auto complete list until i find the function signature that gives me what i need

Proton / wine is modern day magic

Most Windows only steam games work out of the box (you do have to enable it in the right click menu > Compatibility options, per game)

Games that use Anti-cheat aren’t likely to work (it depends on the Anti-cheat used and how it’s configured)

ProtonDB is a good resource for checking if/which games work, or fixes and workarounds

You can use proton or wine on non steam games, but that requires additional setup that I’m not familiar with
