Rust Tutorial

Rust is a modern programming language that is as fast as C and C++, but much safer. It stops whole groups of bugs, such as crashes from bad memory use, before your program even runs.

For many years developers have voted Rust their most loved language. It is used in web browsers, operating systems, game engines, command-line tools and web servers.

Why Learn Rust?

• It gives top speed without a garbage collector
• Its ownership system makes memory errors almost impossible
• Its compiler gives very helpful error messages
• Big companies use it for performance-critical work

What You Will Learn

• Installing Rust and using Cargo
• Variables, mutability, shadowing and data types
• if, match and loops
• Functions and expressions
• Ownership, borrowing and references
• Strings, vectors and hash maps
• Structs, enums, Option and Result

A First Example

fn main() {
    let city = "Karachi";
    let students = 25;
    println!("{} students in {}", students, city);
}

25 students in Karachi

Exercises and Quiz

Each lesson ends with an exercise, and the last lesson is a quiz on the whole tutorial.

What to Learn After Rust

Rust is not the easiest first language. If you find it hard, start with Go or Python, then come back. You may also like Bash for working in the terminal.
