Add a recipe for the cxx crate, which provides a safe and efficient
bridge for interoperability between Rust and C++ code. It allows
defining the FFI boundary in a shared Rust module and generates
compatible bindings for both languages during the build process.
The crate is implemented in Rust and supports zero-overhead FFI with
common Rust and C++ standard library types.

This is mostly just a thought, I don't intend this as a blocker of this
patch. Maybe a loud thought, or a quick-discussion starter?
cxx is pretty generic name, I find it hard to guess that it's a Rust
library for FFI.
Agreed, valid concern.
Debian prefixes this (and similar packages) with librust - this one is
called librust-cxx. Fedora calls it rust-cxx. (Though OpenSuse just
calls it cxx - I guess there is accepted no standard)
What if we would follow Debian or Fedora naming with such Rust
libraries, similar to what is done with many Python and Perl recipes? I
imagine that over time there will be more similar recipes.
librust-cxx seems like the more sensible choice. If there are no
concerns. I'll
send a v2 with the change.

Deepesh
