Ignore function signatures in code coverage report, while not ignore function bodies?

fzyzcjy commented 6 months ago

Given https://github.com/taiki-e/cargo-llvm-cov/issues/327, one work around may be, if we can somehow ignore the function signatures, while keeping the function bodies un-ignored. However, I am not sure whether this is possible currently.

For implementation, one naive way may be:

Users add comments such as // coverage_off_begin and // coverage_off_end (like in other langauges)
Adding a post-processing script, which inputs LCOV report (or whatever), parse the source code, sees (e.g.) line 10-15 is marked ignored by that comment, then change LCOV report by removing those lines.

I prefer to fix the bug itself rather than add an odd workaround to avoid the odd bug.

Totally agree!

Btw I already add workarounds in https://github.com/fzyzcjy/flutter_rust_bridge ...
