Enum AttributeMode 

pub enum AttributeMode {
    Current,
    AtTime,
    Omit,
}

Attribute hydration mode for temporal traversals (§5.2).

Variants

Current

Live attributes from concepts table. Fast. Documented as WRONG for historical text.

AtTime

Attributes as believed at ts, hydrated from transaction_log.

Omit

Topology only; concepts join is omitted.

Use TraversalBuilder::execute_ids, not TraversalBuilder::execute. execute returns Vec<NodeAttributes>, and there are no attributes to return under this mode, so it answers Ok(vec![]) — which a caller cannot tell apart from a traversal that reached nothing. execute_ids returns exactly what this mode is for, and distinguishes the two cases by construction.

Kept rather than removed (Wave 4.5) because it is meaningful where the mode is a parameter — hydrate_attributes and FilteredVectorSearch both take one and are right to accept “no attributes” as a choice. It is only execute’s return type that cannot express it.
