rustUsing box from_raw in Rust

from_raw is a function in Rust that creates a Box from a raw pointer. It takes a raw pointer and a destructor as arguments and returns a Box containing the data pointed to by the raw pointer.

Example:

let ptr = Box::into_raw(Box::new(5));
let boxed = unsafe { Box::from_raw(ptr) };

Output: boxed is a Box containing the value 5.

Code parts:

• Box::into_raw(Box::new(5)): This creates a Box containing the value 5 and returns a raw pointer to the data.
• unsafe { Box::from_raw(ptr) }: This creates a Box from the raw pointer ptr and returns it.
