rustHow to borrow as static in Rust

Static borrowing in Rust is a way to borrow a value without taking ownership of it. This allows the value to be used without having to move it.

let mut x = 5;

{
    let y = &x; // y is a reference to x
    println!("{}", y);
}

x = 6;

Output example

5

The code above shows an example of static borrowing. The variable x is declared as mutable and assigned the value 5. A reference to x is then created and assigned to y. The reference y is then used to print the value of x. Finally, the value of x is changed to 6.

The parts of the code are:

• let mut x = 5;: This declares a mutable variable x and assigns it the value 5.
• let y = &x;: This creates a reference to x and assigns it to y.
• println!("{}", y);: This prints the value of x using the reference y.
• x = 6;: This changes the value of x to 6.
