}

A unified segment that stores all entity types

Required Methods

fn id(&self) -> u64

Get segment ID

fn state(&self) -> SegmentState

Get current state

fn collection(&self) -> &str

Get collection/namespace name

fn stats(&self) -> SegmentStats

Get statistics

fn entity_count(&self) -> usize

O(1) live entity count (entities minus tombstones)

fn contains(&self, id: EntityId) -> bool

Check if entity exists

fn get(&self, id: EntityId) -> Option<&UnifiedEntity>

Get an entity by ID

fn get_mut(&mut self, id: EntityId) -> Option<&mut UnifiedEntity>

Get mutable reference to entity

fn insert(&mut self, entity: UnifiedEntity) -> Result<EntityId, SegmentError>

Insert a new entity

fn update(&mut self, entity: UnifiedEntity) -> Result<(), SegmentError>

Update an existing entity

fn delete(&mut self, id: EntityId) -> Result<bool, SegmentError>

Delete an entity

fn get_metadata(&self, id: EntityId) -> Option<Metadata>

Get metadata for an entity

fn set_metadata( &mut self, id: EntityId, metadata: Metadata, ) -> Result<(), SegmentError>

Set metadata for an entity

fn seal(&mut self) -> Result<(), SegmentError>

Seal the segment (make immutable)

fn should_seal(&self, config: &SegmentConfig) -> bool

Check if should auto-seal based on config

fn iter(&self) -> Box<dyn Iterator<Item = &UnifiedEntity> + '_>

Iterate over all entities

fn iter_kind( &self, kind_filter: &str, ) -> Box<dyn Iterator<Item = &UnifiedEntity> + '_>

Iterate over entities of a specific kind

fn filter_metadata(&self, filters: &[(String, MetadataFilter)]) -> Vec<EntityId>

Search entities by metadata filter

Provided Methods

fn update_hot( &mut self, entity: UnifiedEntity, modified_columns: &[String], ) -> Result<(), SegmentError>

HOT-update: like update but receives the set of field names that actually changed. Allows skipping index work when indexed columns are unaffected. Default: falls back to full update.
