 So, this example clearly shows that to evaluate the safety of types like `Vec`, we have to look at *every single function* provided by that data structure, even if it does not contain any `unsafe` code.

 Why is it the case that a safe function can break `Vec`?
 How can we even say that it is the safe function which is at fault, rather than some piece of `unsafe` code elsewhere in `Vec`?

 That's why I think it's worth dedicating an entire blog post to this point.
 But we are not done yet, we can actually use this observation to learn more about types and type systems.

 The difference between `Vec` and `MyType` is no less significant than the difference between `f32` and `u32`.
 It's just that the compiler has been specifically taught about `f32`, while it doesn't know enough about the semantics of `Vec`.

 At this point, you may be slightly worried about the safety of the Rust ecosystem.
 I just spent two sections arguing that the Rust compiler actually doesn't know what it is doing when it comes to checking functions that work on `Vec`.
