hope this talk results in the improvement of Rust for everyone! Introduction Language Library Tooling Nightly features A general priority is to stabilize them (or to find alternatives): https://github RUSTC_BOOTSTRAP. The rest of this talk focuses on things that are not in nightly.

Tooling: In addition to great IDE support in general, Kotlin offers framework-specific tooling (for example, for Spring) in the plugin for IntelliJ ensuring that Kotlin applications can run on older Android devices with no issues. The Kotlin tooling is fully supported in Android Studio and compatible with the Android build system. Performance:
