It looks like this pull request may not have tests. Please make sure to add tests or get an explicit test exemption before merging.

If you are not sure if you need tests, consider this rule of thumb: the purpose of a test is to make sure someone doesn't accidentally revert the fix. Ask yourself, is there anything in your PR that you feel it is important we not accidentally revert back to how it was before your fix?

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing. If you believe this PR qualifies for a test exemption, contact "@test-exemption-reviewer" in the #hackers channel in Discord (don't just cc them here, they won't see it!). The test exemption team is a small volunteer group, so all reviewers should feel empowered to ask for tests, without delegating that responsibility entirely to the test exemption group.

Code Review

This pull request introduces several minor fixes for compatibility with libstdc++ 15. The changes primarily involve adding necessary headers like <cstdint> and <memory> to various files, ensuring they are self-contained. Additionally, the API for Filter::Open has been updated to use std::string instead of std::string_view for file paths, which is a valid approach to resolve issues with std::ifstream. My review includes suggestions to refine this API change by using a const reference for the string parameter, which is a standard practice to prevent unnecessary copies and aligns with the project's C++ style guide.

I don't understand this change. Why not just a std::string_view reference (with an include of <string_view>`?

std::ifstream::open() does not accept a std::string_view argument
