If a piece of code does not panic in panic=unwind, then it does not panic in panic=abort either. So having coverage of panic=unwind would be sufficient to guarantee that code cannot panic. The caveat you mention with panic=abort would only

I think about pull requests the same way: As a library maintainer, closing and empathetically conveying why a pull request is not a net benefit to the project is an order of magnitude more effort than what it takes to throw up not-well-moti

Not automatic, but it already supports a measure of "how much" you depend on a project: boosting. You can boost dependencies up or down by up to a factor of 20 (e^3). The formula is explained in https://thanks.dev/

Currently 2863 crates (2.6% of crates). Note that the search you linked also includes crates that only have "rust" in the description or readme, not just the crate name -- that is why it shows a much higher count.

I used it with great success for transpiring libyaml from C to Rust. I even set up Miri to run the upstream library's entire transpiled test suite, and the fact it passes is validation of absence of UB in the original C code. The trans
