rustHow to get pointer of object in Rust

In Rust, you can get a pointer to an object by using the & operator. For example, if you have an object my_object of type MyObject, you can get a pointer to it by writing &my_object. This will return a pointer of type &MyObject. You can then use this pointer to access the object's fields and methods. Additionally, you can use the Box type to create a pointer to an object on the heap. For example, let my_box = Box::new(my_object); will create a pointer to my_object on the heap.

struct MyObject {
    field1: i32,
    field2: i32,
}

fn main() {
    let my_object = MyObject { field1: 1, field2: 2 };
    let my_pointer = &my_object;
    let my_box = Box::new(my_object);

    println!("Pointer to my_object: {:?}", my_pointer);
    println!("Box containing my_object: {:?}", my_box);
}

Output example

Pointer to my_object: &MyObject { field1: 1, field2: 2 }
Box containing my_object: Box { 0: MyObject { field1: 1, field2: 2 } }

Explanation

The & operator is used to get a pointer to an object. In this example, my_pointer is a pointer to my_object. The Box type is used to create a pointer to an object on the heap. In this example, my_box is a pointer to my_object on the heap.
