rust-bindgen

It mostly scores a "YES", where there are footnotes. AFAIK all of these things are being worked on. > Does it support all of the following architectures? x86_64, ARM, MIPS, powerPC It does: https://doc.rust-lang.org/book/getting-started.html#tier-2. Granted, while tier 2 support is pretty good, it isn't the same level of support as the tier 1 platforms. > Does it support soft float? From running `rustc -C help`: -C soft-float -- use soft float ABI (*eabihf targets only) > Can it link against uclibc instead of glibc? It can link against musl, but I'm not sure whether that would enable uclibc. Probably? > Can it link against arbitrary C libraries? Yes. > Can I use a C library's header.h file without having to hand-recode it to Rust? You can use something like rust-bindgen (https://github.com/Yamakaky/rust-bindgen) which

It looks like the first part of what you want is nearly there - see https://github.com/Yamakaky/rust-bindgen It converts C headers to a Rust module containing the relevant type/function/etc. definitions. On stable you need to either pregenerate the module (not too bad if you're pinning particular versions of libraries anyway) or add a build script to autogenerate it. On nightly, there's also a compiler plugin that does all the work for you, and looks not-too-dissimilar to what you wanted. The only thing it lacks is the prefix removal stuff.

There are C library binding generators for Rust which do the boring work for you. It's not perfect, but rust-bindgen was pretty good last time I tried it (~15 months ago): https://github.com/Yamakaky/rust-bindgen
