Emit a "manual" implementation of Debug when it cannot be derived

[fitzgen]

Could initially just print the type's name as a placeholder.

Could eventually print the fields within the type that are Debug and placeholders for the fields that aren't.

Should be behind a new option.

Can you point a place where to start looking?

[bkchr]

Ahh, I think I found it :)

[fitzgen]

@bkchr yep! Let me know if you have any other questions :)

[bkchr]

I use cargo test --features testing_only_libclang_4 to run the tests. Is it normal that the expectation files are modified by the test case?
Are there also some tests that try to compile the generated rust files?

[bkchr]

Okay, I answered the question myself. ^^
Using cd tests/expectations && cargo test, compiles and tests the generated files.

[fitzgen]

Is it normal that the expectation files are modified by the test case?

Yes, this is to make it easier to update test expectations when making changes that modify their output, and its easy enough to git checkout -- tests/expectations to remove the modifications if they're undesired.

Are there also some tests that try to compile the generated rust files?

Yeah, I had thought this was documented in CONTRIBUTING.md, but it doesn't seem to be. I need to fix that.

[bkchr]

It is documented in the Contribution.md, but the command, written there, does not work. Or at least did not worked for me ^^

[bkchr]

I think that can now be closed @fitzgen ?

[fitzgen]

Yes, thanks! Were you interested in hacking on some other bindgen issues? We have plenty, if you're looking :)
