- `Box` is like `std::unique_ptr` in C++, except that it's guaranteed to be not
null.
- A `Box` can be useful when you:
- have a type whose size that can't be known at compile time, but the Rust
compiler wants to know an exact size.
- have a type whose size can't be known at compile time, but the Rust compiler
wants to know an exact size.
