Struct SpatialIndexManager 

pub struct SpatialIndexManager { /* private fields */ }

Manages per-collection R-tree spatial indexes.

Each collection that has geometry fields gets its own R-tree. The field name is stored alongside so we know which document field to extract geometry from.

Implementations

impl SpatialIndexManager

pub fn new() -> Self

pub fn index_document( &mut self, collection: &str, field: &str, doc_id: &str, geometry: &Geometry, )

Index a geometry from a document. If the document already has an entry, it is removed first (upsert semantics).

pub fn remove_document(&mut self, collection: &str, field: &str, doc_id: &str)

Remove a document’s geometry from the index.

pub fn search( &self, collection: &str, field: &str, query: &BoundingBox, ) -> Vec<&RTreeEntry>

Range search: find all document entry IDs whose bbox intersects the query.

pub fn nearest( &self, collection: &str, field: &str, lng: f64, lat: f64, k: usize, ) -> Vec<NnResult>

Nearest-neighbor search.

pub fn is_empty(&self) -> bool

Number of indexed entries across all collections. Whether no spatial indices exist.

pub fn total_entries(&self) -> usize

pub fn collection_count(&self) -> usize

Number of indexed collections.

pub fn checkpoint_all(&self) -> Vec<(String, String, Vec<u8>)>

Checkpoint all R-trees to bytes for persistence.

Returns a vec of (collection, field, rtree_bytes).

pub fn restore_all(checkpoints: &[(String, String, Vec<u8>)]) -> Self

Restore R-trees from checkpoint data.

Takes a vec of (collection, field, rtree_bytes).

pub fn rebuild_from_documents( &mut self, collection: &str, field: &str, documents: &[(String, Geometry)], )

Rebuild spatial index from a collection of documents.

Scans all documents, extracts geometry from the specified field, and builds the R-tree.

Trait Implementations

impl Default for SpatialIndexManager

fn default() -> Self

Returns the “default value” for a type.
