How do you import and reference enum types in Rust?

Question

How do you import and reference enum types from the Rust std lib?

I\'m trying to use the Ordering enum from the std::sync::atomics module.

Enum variants are not scoped inside the enum; they are thus std::sync::atomics::Relaxed, &c.

Scoped enum variants is the subject of issue 10090.
