Using Rust in Your Next KMP App
summary
Rust gets integrated into a Kotlin Multiplatform app to move performance‑sensitive logic into a safe native layer, using rustup and cargo to build a static lib, Kotlin/Native C interop plus the Android NDK and JNI to bridge JVM code, and Xcode to link the iOS framework. The demo compiles for four Android ABIs and three iOS targets, required copying liḃshared.so into jniLibs, and wires a simple add_numbers function end‑to‑end; native breakpoints hit in Rust but continuation is limited, and unsafe glue is necessary for FFI.
