rustHow to send box in Rust
Sending a box in Rust is a simple process. To do so, you must first create a Box
type with the Box
keyword.
let my_box = Box::new(5);
This creates a box containing the value 5
. To send the box, you must use the std::mem::swap
function.
let mut target = 0;
std::mem::swap(&mut target, &mut my_box);
This swaps the contents of target
and my_box
, effectively sending the box.
- Create a
Box
type with theBox
keyword:let my_box = Box::new(5);
- Use the
std::mem::swap
function to swap the contents oftarget
andmy_box
:std::mem::swap(&mut target, &mut my_box);
