When an enum is C-like, you can apply the `as` cast operator to
convert it to its discriminator value as an `int`.
<a name="single_variant_enum"></a>
There is a special case for enums with a single variant, which are
sometimes called "newtype-style enums" (after Haskell's "newtype"
feature). These are used to define new types in such a way that the
new name is not just a synonym for an existing type, but its own
distinct type: `type` creates a structural synonym, while this form of
`enum` creates a nominal synonym. If you say:
~~~~
enum GizmoId = int;
~~~~
That is a shorthand for this:
~~~~
enum GizmoId { GizmoId(int) }
~~~~
You can extract the contents of such an enum type with the
dereference (`*`) unary operator:
~~~~
# enum GizmoId = int;
let my_gizmo_id: GizmoId = GizmoId(10);
let id_int: int = *my_gizmo_id;
~~~~
Types like this can be useful to differentiate between data that have
the same type but must be used in different ways.
~~~~
enum Inches = int;
enum Centimeters = int;
~~~~
The above definitions allow for a simple way for programs to avoid
confusing numbers that correspond to different units.
For enum types with multiple variants, destructuring is the only way to
get at their contents. All variant constructors can be used as
patterns, as in this definition of `area`:

Rust also has _nominal tuples_, which behave like both structs and tuples,
