Macros in RUST

Macros in RUST

Macros are a way to generate code at compile time. They can be used for code generation or to create domain-specific languages within Rust. Here's an example of a simple macro:

macro_rules! add_five {

    ($x:expr) => ($x + 5);

}

fn main() {

    let x = 10;

    let result = add_five!(x);

    println!("The result is {}", result);

}
