Struct PropertyStorage 

pub struct PropertyStorage<Id: EntityId = NodeId> { /* private fields */ }

Columnar property storage.

Properties are stored in a columnar format where each property key has its own column. This enables efficient filtering and scanning of specific properties across many entities.

Generic over the entity ID type (NodeId or EdgeId).

Implementations

impl<Id: EntityId> PropertyStorage<Id>

pub fn new() -> Self

Creates a new property storage.

pub fn set(&self, id: Id, key: PropertyKey, value: Value)

Sets a property value for an entity.

pub fn get(&self, id: Id, key: &PropertyKey) -> Option<Value>

Gets a property value for an entity.

pub fn remove(&self, id: Id, key: &PropertyKey) -> Option<Value>

Removes a property value for an entity.

pub fn remove_all(&self, id: Id)

Removes all properties for an entity.

pub fn get_all(&self, id: Id) -> FxHashMap<PropertyKey, Value>

Gets all properties for an entity.

pub fn column_count(&self) -> usize

Returns the number of property columns.

pub fn keys(&self) -> Vec<PropertyKey>

Returns the keys of all columns.

pub fn column(&self, key: &PropertyKey) -> Option<PropertyColumnRef<'_, Id>>

Gets a column by key for bulk access.

pub fn might_match( &self, key: &PropertyKey, op: CompareOp, value: &Value, ) -> bool

Checks if a predicate on a property might match any values.

Returns true if the property column might contain matching values, false if it definitely doesn’t. Returns true if the property doesn’t exist.

pub fn zone_map(&self, key: &PropertyKey) -> Option<ZoneMapEntry>

Gets the zone map for a property column.

pub fn rebuild_zone_maps(&self)

Rebuilds zone maps for all columns (call after bulk removes).

Trait Implementations

impl<Id: EntityId> Default for PropertyStorage<Id>

fn default() -> Self

Returns the “default value” for a type.
