@rafaelcaricio and I are creating #RustLang Bindings for #LittlevGL... So creating fancy Watch Faces and Watch Apps gets easier on #PineTime @PINE64 ! Stay tuned here (apologies my Rust code isn't really idiomatic yet)...

Static Variables in C can create strange problems... Here's how Rust prevents them! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Some things in C shouldn't be passed via the Stack... Rust prevents that by checking Lifetimes! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Strings are Safer in Rust than in C... Here's why! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

I'm using bloated Bezier Paths too for #RustLang on #PineTime @ThePine64... 🤔

Unlike C, Rust forces you to check for errors returned by functions! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Handling Errors in C is messy... Here's how we do it in Rust! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

C Functions made safer in Rust... Via Procedural Macros! Learn #RustLang on @RIOT_OS and create #PineTime Watch Faces @PINE64 with #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Rust Safe Wrappers to make C Functions a little safer... That's how we create crash-proof #PineTime Watch Faces @PINE64 with #RustLang on @RIOT_OS and #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Whitelist and Blacklist C Functions imported into Rust... Create #PineTime Watch Faces @PINE64 with #RustLang, bindgen, @RIOT_OS and #LittlevGL https://lupyuen.github.io/PineTime-apps/articles/watch_face

Import C Libraries into Rust the easy way... With bindgen! That's how we imported the #LittlevGL Library into #PineTime Watch Faces @PINE64 built with #RustLang on @RIOT_OS https://lupyuen.github.io/PineTime-apps/articles/watch_face
