#RustLang Ownership, Borrowing, and Lifetimes... What are they? Why do they made coding safer?

@veer66 yes Rust Procedural Macros are truly awesome! I used them to do type inference in my variant of Rust called "Typeless Rust". Which is really useful for Visual Rust programming because we don't want newbies to fill in all the missing types: https://medium.com/@ly.lee/advanced-topics-for-visual-embedded-rust-programming-ebf1627fe397?sk=01f0ae0e1b82efa9fd6b8e5616c736af

Folks on #Mastodon seem friendlier and more inquisitive... Bad news for #Twitter 🤔 https://joinmastodon.org/

@clacke @PINE64 ...Microsoft repackaged Blockly as Makecode, the web builder toolkit for BBC micro:bit. That's why I was inspired to bring Blockly to #PineTime 🙂

@clacke @PINE64 Very sharp... Must be a Millennial who grew up with Scratch 🙂

Scratch started as a project at MIT Media Lab... Google open-sourced it as Blockly (which I'm using).

Blockly will convert visuals blocks into all kinds of code: JavaScript, Python, Lua, PHP, Dart... Anything but Rust!

So I had to build the Rust Code Generator for Blockly myself... Not that hard 🙂

@veer66 ...So don't blame yourself if your brains hurt from looking at C Macros! 😉

Why are C Macros hard? Because they are a form of Metaprogramming. So are #RustLang Macros

@veer66 Exactly! Why are C Macros hard? Because they are a form of Metaprogramming! So are #RustLang Macros

What's #Metaprogramming? That's when you write a program that generates another program... Like here when I'm designing a graphical program (in Blockly) that will generate a #RustLang program for #PineTime Smart Watch @PINE64 ... https://developers.google.com/blockly/guides/overview
