Embedding Rust in C/C++
summary
Concrete recipes for embedding Rust inside existing C/C++ code appear: use extern "C" and no_mangle to expose symbols, add crate-type like cdy lib or staticlib, generate headers with the mentioned sea pines gem, and run cargo then your C/C++ linker. Memory uses Box and Box::into_raw so C holds pointers; errors map to Result-like structs or C double-pointer patterns. A C shim can call into Rust and a small C shim plus careful linking makes throwing C++ exceptions from Rust work but depends on compiling with a C++ toolchain.
