Managing packages, dependencies, and testing with Cargo
The fn main() entry point and println! macro

Introduction & Core Concept

Rust is a systems programming language focused on safety, speed, and concurrency. It achieves memory safety at compile time without a runtime garbage collector.

WHY DOES THIS MATTER IN THE REAL WORLD?

Over 70% of security vulnerabilities in C/C++ are memory safety bugs (buffer overflows, use-after-free). Rust mathematically eliminates these at compile time.
