Why Rust ? Code Smarter Not Harder 😎

Rust is a powerful programming language designed for performance, safety, and concurrency. This concise guide introduces Rust’s key concepts, complemented by code examples to kickstart your Rust journey. Let’s explore the fundamentals of Rust, enriched with snippets of code.

1. Introduction to Rust

Rust is known for its guarantees of memory safety and speed. It uniquely features ownership, borrowing, and lifetimes to manage memory.

2. Memory Safety Principles

Rust’s compiler checks ensure memory safety, preventing common errors like buffer overflows.

3. The Ownership System

Ownership is a core feature. When a variable goes out of scope, Rust automatically cleans up its resources.

fn main() {
    let s = String::from("hello"); // s owns the string
} // s goes out of scope, and the memory is freed

4. Borrowing and References

Rust uses references for borrowing, ensuring data is not simultaneously mutated and read elsewhere.

fn main() {
    let s1 = String::from("hello");
    let len = calculate_length(&s1);
    println!("The length of '{}' is {}.", s1, len);
}

fn calculate_length(s…
