#learningrust — Public Fediverse posts

Thanks to the bank holiday (in Germany) I had some time to finish the third part of my **Learning Rust** post series!

This part is all about structs, tuples and (crazy) enums!

And of course some MIRs again, what else?

Ah, yet another aspiring "author" 📝 thinks the world needs a #book about #Ruby that it never asked for. But don't worry, it'll be ready sometime before the heat death of the universe. 🚀 Why bother with actual #innovation when you can just repackage the same boring tech jargon with a sprinkle of "I'm learning Rust"? 🙄

Understanding string slicing in #RustLang 🦀:

Remember: slices are based on bytes, not characters! Slicing an ASCII string is different from slicing a multibyte Unicode string. If you slice incorrectly, Rust will panic at runtime. ⚠️

let multibyte_string = "España";
let slice_multibyte = &multibyte_string[..5]; // This will panic! 🚫

Ensure your slices align with valid UTF-8 character boundaries.
