Google has pledged a $1 million grant to improve Rust and C++ interoperability, launching an Interop Initiative that aims to enhance ABI compatibility, tooling, and wrapper libraries while promoting Rust’s memory‑safety benefits across Android and other Google products.
This article explains the low‑level mechanics of extern "C", why placing #include directives inside an extern "C" block can cause name‑mangling and linkage errors, and provides practical guidelines and code examples for safely mixing C and C++ headers.
Google’s newly unveiled Carbon language, positioned as an experimental successor to C++, promises modern language features, seamless C++ interoperability, and a path for developers to write performance‑critical software while avoiding many of Rust’s ownership complexities.
CGO lets Go programs call C functions and vice versa by importing "C", generating intermediate files, handling type conversion, managing runtime transitions, and requiring careful memory and pointer handling, with best‑practice guidelines to avoid leaks, scheduler issues, and thread explosion.
