How To Integrate Rust Into A React Native App
summary
Describes a concrete recipe to call Rust from React Native: implement a JSI Promise bridge in C++ that maps promise IDs, use the cxx + Tokio runtime to run async Rust tasks, and call back into C++ to resolve or reject the original JS Promise. Shows replacing a gRPC C++ layer, reducing nested callbacks, and avoiding memory-safety bugs via Rust’s borrow checker. Demo runs an add across languages (9 + 21 → 30), proving the pipeline works end to end.
