Rust

fn main() {
    println!("This is Rust");
}

Rust is a memory-safe, compiled programming language that combines high-level simplicity, with low-level performance. A popular choice for systems where performance is absolutely critical like:

• Game Engines
• Databases
• Operating Systems

It was created in 2007, and named after the “Rust Fungus” 🌐 plant disease.

Rust was then sponsored by Mozilla in 2009, and has been ranked the #1 most-loved programming language every year since 2016.

Memory Safety

Usually high-level languages provide a “garbage collector” to free up memory not in use anymore, while lower-level languages provide functions like free and reallocto reallocate memory yourself. Rust has no “garbage collector”, but still achieves “memory safety” with the concept of “Ownership” and “Borrowing”.

• Every value in Rust is assigned to a single variable, known as its “owner”
• If that variable goes out of scope, the memory allocated to it is dropped automatically
• If you want to pass that variable to a different part of the program, “borrowing” allows you to access a reference in memory, without taking ownership of it.

Additionally Rust has a whole set of rules which a “Borrow Checker” validates at compile time, to ensure your code is safe.

Cargo

Rust has its own package manager, called cargo, where each individual package is called a crate
