rustHow to get box value in Rust

Getting the value of a box in Rust is done by using the deref method. This method returns a reference to the value stored in the box.

Example code:

let x = Box::new(5);
let y = *x;
println!("{}", y);

Output:

5

The code above creates a box with the value 5 and then uses the deref method to get the value stored in the box. The * operator is used to dereference the box and get the value. The value is then printed using the println! macro.

Code parts:

• let x = Box::new(5);: creates a box with the value 5
• let y = *x;: uses the deref method to get the value stored in the box
• println!("{}", y);: prints the value using the println! macro
