Struct SpatialResultMerger 

pub struct SpatialResultMerger { /* private fields */ }

Merges spatial results from multiple shards.

For boolean predicates (ST_Contains, ST_Intersects): simple concatenation. For distance predicates (ST_DWithin): merge and sort by distance, take limit.

Implementations

impl SpatialResultMerger

pub fn new(expected_shards: usize) -> Self

pub fn add_shard_result(&mut self, result: &ShardSpatialResult)

Add a shard’s results.

pub fn all_responded(&self) -> bool

Whether all expected shards have responded.

pub fn merge(&mut self, limit: usize, sort_by_distance: bool) -> Vec<SpatialHit>

Merge all results: deduplicate by doc_id, optionally sort by distance.

For ST_DWithin, results are sorted by distance (nearest first). For boolean predicates, order is arbitrary. Truncates to limit.

pub fn total_hits(&self) -> usize

Total hits collected (before merge).

pub fn response_count(&self) -> usize
