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.

DESCRIPTION = "cxx is a library that enables safe and efficient interoperability \
|
|
between Rust and C++ code. It defines the FFI boundary in a single \
|
|
Rust module, allowing static analysis of types and function signatures \
|
|
for compatibility and safety. The library generates the necessary Rust \
|
|
and C++ bindings automatically during the build process. It provides near \
|
|
zero-overhead integration and supports idiomatic use of common Rust and C++ \
|
|
standard library types."
