Rust Boxed values Using Boxed Values
Example
Because Boxes implement the Deref<Target=T>, you can use boxed values just like the value they contain.
let boxed_vec = Box::new(vec![1, 2, 3]);
println!("{}", boxed_vec.get(0));
If you want to pattern match on a boxed value, you may have to dereference the box manually.
struct Point {
x: i32,
y: i32,
}
let boxed_point = Box::new(Point { x: 0, y: 0});
// Notice the *. That dereferences the boxed value into just the value
match *boxed_point {
Point {x, y} => println!("Point is at ({}, {})", x, y),
}
