TemporalIndexRule

hirn_exec::rules::temporal_index

Struct TemporalIndexRule 

Source 
pub struct TemporalIndexRule;
Expand description

Pushes temporal predicates into scan nodes for Lance BTree index utilization.

Currently this rule is a structural placeholder that identifies filter→scan patterns with temporal predicates. The actual pushdown into Lance scans (via LanceTableProvider filter pushdown) is wired in Epic 5.
