13 The `extern "Rust"` section of a CXX bridge declares Rust types and signatures
16 The CXX code generator uses your extern "Rust" section(s) to produce a C++

25 Types defined in Rust that are made available to C++, but only behind an

40 way. Rust code created the `MultiBuf`, passed a `&mut MultiBuf` to C++, and C++
41 later passed a `&mut MultiBuf` back across the bridge to Rust.
44 exposes the Rust standard library's `std::fs::File` to C++ as an opaque type in
54 opaque Rust type. These restrictions may be lifted in the future.
