Rust Basics

Rust is a modern programming language focused on safety, speed, and concurrency. It allows developers to write programs that are memory-safe without a garbage collector. Rust is particularly known for its ownership system, which prevents common bugs like null pointer dereferences and data races at compile time.

Rust works closely with other languages and technologies:

• System Programming – Rust is used for low-level systems development, similar to C and C++, allowing precise control over memory and performance.
• WebAssembly – Rust can compile to WebAssembly, enabling high-performance code to run in the browser alongside JavaScript.
• Back-end Development – Rust powers server applications and APIs, often replacing languages like Go, C++, or Java for performance-critical tasks.
• Concurrency – Rust’s ownership and borrowing rules make multithreaded programming safe and efficient.
• Frameworks & Libraries – Rust has libraries like Rocket (web) and Actix (server), plus crates for data processing, networking, and more.
