alt Hacker Newsin the first example:
```
10: rjk::duck<Container> c{std::vector<int>{1, 2, 3}};
11: c.size(); // 3
12:
13: c = std::string{"hello"};
```
Does the assignment on line 13 call the destrucor for the vector of ints created on line 10?

Is there another option? Or were you asking if it leaks memory?
Maybe you were asking if it implements custom destructors? GC?

Yes. duck takes ownership of the vector by moving it into its internal storage.
As a bonus, if you tried passing in an lvalue, it will reject the input unless you add the "copyable" trait, so it ends up mitigating some hidden copies.
