7```rust
8extern crate thin_slice;
9
10use std::mem;
11use thin_slice::ThinBoxedSlice;
12
13struct Ticket {
14 numbers: Box<[u8]>,
15 winning: bool,
16}
17
18struct ThinTicket {
19 numbers: ThinBoxedSlice<u8>,
20 winning: bool,
21}
22
23fn main() {
24 let nums = vec![4, 8, 15, 16, 23, 42].into_boxed_slice();
25 let ticket = ThinTicket {
26 numbers: nums.into(),
27 winning: false,
28 };
29 println!("Numbers: {:?}", ticket.numbers);
30
31 println!("size_of::<usize>(): {}", mem::size_of::<usize>());
32 println!("size_of::<Ticket>(): {}", mem::size_of::<Ticket>());
33 println!("size_of::<ThinTicket>(): {}", mem::size_of::<ThinTicket>());
34}
