LIVE Rust: Learning Vectors, Strings & HashMaps with @JetBrainsTV Academy

In this live stream, we dive deep into how data structures like Vectors, Strings, and HashMaps work in Rust while working through exercises on JetBrains Academy.

Whether you're a beginner or looking to solidify your understanding of Rust's memory management and data handling, this session covers it all.

What we cover:
- Collections in Rust: Strings, HashMaps, Options
- Error Handling
