Does Rust compile code that can be used/called from other languages with an FFI? That to me is always one of the persistent advantages of C, I don't have to fully understand how compile machine code works on a technical level, but there are lots of different languages that let me use C libraries in their own language runtimes.

It would be great to have things like high-performance unicode handling with consistent semantics across multiple languages!

Yes it does -- one of the great parts about Rust. There are lots of projects out there slotting rust into other languages and getting crazy speedups.

A few days ago I read https://dev.to/veer66/calling-rust-from-common-lisp-45c5 , which illustrates presumably what you're talking about.

Yes, from the python side of things there are tools like py03 that make integrating rust into python code really painless.

I have a sql parsing library (shameless plug) that is 50x faster than any other python implementation, it is just a super simple wrapper around a rust crate.

Yes, you can expose things with the C ABI. This is essential for how it's used in Firefox.

Yes, Rust natively can expose C ffi functions (for example).

The https://cxx.rs/ project is also a major crate for C++ interoperability.
