Struct PropertyPredicate 

pub struct PropertyPredicate { /* private fields */ }

A property-based predicate for factorized data.

Evaluates a condition on an entity’s property (node or edge).

Performance

Uses direct property lookup via LpgStore::get_node_property() which is O(1) per entity. This avoids the O(properties) overhead of loading all properties when only one is needed.

Implementations

impl PropertyPredicate

pub fn new( level: usize, column: usize, property: impl Into<PropertyKey>, op: CompareOp, value: Value, store: Arc<LpgStore>, ) -> Self

Creates a new property predicate.

pub fn eq( level: usize, column: usize, property: impl Into<PropertyKey>, value: Value, store: Arc<LpgStore>, ) -> Self

Creates an equality predicate on a property.

Trait Implementations

impl FactorizedPredicate for PropertyPredicate

fn evaluate_batch( &self, chunk: &FactorizedChunk, level: usize, ) -> LevelSelection

Batch evaluates the predicate for all physical indices at a level.

This is more cache-friendly than individual evaluations for large batches.

fn evaluate( &self, chunk: &FactorizedChunk, level: usize, physical_idx: usize, ) -> bool

Evaluates the predicate for a single physical index at a level.

fn target_level(&self) -> Option<usize>

Returns the level this predicate operates on.
