EditReport

Rust is a modern systems programming language focused on speed, memory safety, and concurrency.

It helps developers build fast and reliable software while preventing common programming errors like null pointer dereferencing and memory leaks.

Features of Rust

• Fast and memory-efficient
• Memory safety without garbage collection
• Fearless concurrency
• Modern tooling with Cargo
• Cross-platform support

Simple Rust Program

fn main() {
    println!("Hello, Rust!");
}

Explanation

• fn main() is the entry point of the program.
• println!() prints output to the console.
• Rust uses {} braces to define blocks of code.

Rust is widely used in systems programming, web assembly, game engines, embedded systems, and backend development.
