| There are three types of structures ("structs") that can be created using the | |
| `struct` keyword: | |
| * Tuple structs, which are, basically, named tuples. | |
| * The classic [C structs](http://en.wikipedia.org/wiki/Struct_(C_programming_language) | |
| * Unit structs, which are field-less structs. | |
