Hosting a #RustLang App on @RIOT_OS is not that hard! Check out this build script for #PineTime Smart Watch @PINE64 ... https://github.com/lupyuen/PineTime-apps/blob/master/scripts/build-app.sh

Rust Watch Face with #LittlevGL for #PineTime Smart Watch @PINE64 ... No more compiler errors and warnings yay! Now linking the #RustLang binaries with @RIOT_OS https://github.com/lupyuen/PineTime-apps/blob/master/rust/app/src/screen_time.rs

Fight the Rust Compiler... Now only 1 error yay! 1️⃣ #RustLang Compiler is fast (under 2 sec) even with Proc Macros 2️⃣ Compiler checks every para for string formatting ("sprintf") 3️⃣ Works great on #Embedded #RTOS like @RIOT_OS on #PineTime @PINE64 https://github.com/lupyuen/PineTime-apps/blob/master/rust/app/src/screen_time.rs
