Struct SpatialRoutingTable 

pub struct SpatialRoutingTable { /* private fields */ }

Per-collection spatial routing metadata.

Tracks which shards have spatial data and their extent. Used by the coordinator to avoid fanning out to shards that can’t possibly match.

Implementations

impl SpatialRoutingTable

pub fn new() -> Self

pub fn update_extent( &mut self, collection: &str, shard_id: u16, extent: Option<BoundingBox>, entry_count: usize, )

Update the spatial extent for a shard.

pub fn route_query( &self, collection: &str, query_bbox: &BoundingBox, all_shard_ids: &[u16], ) -> Vec<u16>

Find which shards might contain results for a spatial query.

Returns shard IDs whose extent overlaps the query bounding box. If no extent data is available for a shard, it is conservatively included (we don’t know what’s there, so we must check).

pub fn total_entries(&self, collection: &str) -> usize

Get the total number of spatial entries across all shards for a collection.

Trait Implementations

impl Default for SpatialRoutingTable

fn default() -> Self

Returns the “default value” for a type.
