rustHow to borrow with lifetime in Rust

Rust provides a powerful feature called 'lifetimes' which allows you to borrow data from one part of your code and use it in another. This is done by specifying a lifetime for a reference, which is a period of time during which the reference is valid.

fn main() {
    let x = 5;
    let y = &x;
    println!("x = {}", x);
    println!("y = {}", y);
}

Output example

x = 5
y = 5

The code above shows how to borrow with lifetime in Rust. The let x = 5 statement creates a variable x with the value 5. The let y = &x statement creates a reference y to the variable x. The & symbol is used to create a reference. The lifetime of the reference y is the same as the lifetime of the variable x.

List of ## Code explanation

• let x = 5: creates a variable x with the value 5
• let y = &x: creates a reference y to the variable x
• & symbol: used to create a reference
• println!("x = {}", x): prints the value of x
• println!("y = {}", y): prints the value of y
