Rust – Systems Programming Language

Rust is a systems programming language focused on safety, speed, and concurrency. It achieves memory safety without garbage collection, making it ideal for performance-critical applications.

Key Features

• Memory Safety: No null pointers or data races
• Zero-Cost Abstractions: High-level syntax, low-level speed
• Ownership System: Compile-time memory management
• Cargo: Integrated package manager and build tool
• Cross-Compilation: Build for multiple targets

Installation

Install Rust using rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env
rustc --version

Usage Examples

Rust programming examples:

use std::fs;

fn main() {
    // File reading with error handling
    let contents = fs::read_to_string("file.txt")
        .expect("Failed to read file");
    
    // Ownership and borrowing
    let s1 = String::from("hello");
    let len = calculate_length(&s1);
    println!("Length of '{}' is {}", s1, len);
}

fn calculate_length(s: &String) -> usize {
    s.len()
}

Benefits

Rust prevents common bugs at compile time while matching C/C++ performance. Its growing ecosystem makes it viable for web services, embedded systems, and CLI tools.
