Key Points:
* Structs work like in C or C++.
* Like in C++, and unlike in C, no typedef is needed to define a type.
* Unlike in C++, there is no inheritance between structs.
* Methods are defined in an `impl` block, which we will see in following slides.
* This may be a good time to let people know there are different types of structs.
* Zero-sized structs `e.g., struct Foo;` might be used when implementing a trait on some type but don’t have any data that you want to store in the value itself.
* The next slide will introduce Tuple structs.
