fn main() {
let mut vec = vec![1, 2, 3];
let mut my_vec2 = vec![236, 149, 136, 235, 133, 149, 32];
vec.append(&mut my_vec2);
println!("{vec:?}");
}
결과

Vec in std::vec - Rust
Consumes and leaks the Vec, returning a mutable reference to the contents, &'a mut [T]. Note that the type T must outlive the chosen lifetime 'a. If the type has only static references, or none at all, then this may be chosen to be 'static. As of Rust 1.57
