Struct Occurrence 

pub struct Occurrence {
    pub type_name: &'static str,
    pub arity: usize,
    pub predefined_slot: Option<usize>,
    pub members: &'static [&'static str],
    pub type_class: Option<&'static str>,
}

One occurrence class: its slots, enum, and permitted type.

Fields

type_name: &'static str

STEP type name, upper-case as stored.

arity: usize

Total attribute count, including inherited.

predefined_slot: Option<usize>

Slot holding PredefinedType, or None when the class has none.

members: &'static [&'static str]

Permitted PredefinedType tokens; empty when there is no enum.

type_class: Option<&'static str>

The one type class CorrectTypeAssigned permits, if any.
