`std::os::raw` has recently been moved/duplicated to `core::ffi` under an unstable feature flag, tracking issue here: https://github.com/rust-lang/rust/issues/94501

Yeah well, I thought about it a year ago, and it took me a year... Anyhow, wonderful that you're on board! I might whip up a PR at some point,...

I know how it is, don't stress, I don't mind if it takes a few months!

Wonderful, no worries about the merge mistake, happens to the best of us ;) This PR is fairly close to serviceable now (just need to do a new release of...

I've tried to include `git` attribution where possible, really couldn't have done it without all of the amazing...

My three cents on some of the still open questions here. **Stability of ident hashing:** This is also [done in the `defmt` crate](https://github.com/knurling-rs/defmt/blob/defmt-v0.3.1/macros/src/construct.rs), so at least it's not unheard of,...
