Google To Allow Rust Code In The Chromium Browser
Google is working to introduce a production Rust toolchain into their build system for Chromium and will be allowing Rust libraries for use within Chrome/Chromium. The timeframe for getting this all together is expected within the next year following a slow ramp.
Google is backing Rust for Chromium to allow for simpler and safer code than "complex C++" overall, particularly around avoiding memory safety bugs. In turn using Rust should help speed-up development and improve overall security of the Chrome web browser.
Initially they are focused on supporting interop in a single direction from C++ to Rust and for now will only be supporting third-party libraries for their Rust usage.
