windows-core: Error handling for Free/Owned<T> #3682
Description
Suggestion
Most functions used to free handles can return errors and these errors are usually indicative of logic errors in the code. Unfortunately when using Owned<T> and/or Free there is no way to detect these errors.
It would be nice if Free::free() had some way to return errors. Even a basic Result<(), ()> to indicate the presence or absence of an error would be very useful.
As for Owned<T>, it would be nice if it had some kind of assertion to panic on error in drop, but this is a more risky proposal, since unexpected panics are quite destructive. Perhaps it could be a debug assertion.
