Struct GeoEngine 

pub struct GeoEngine { /* private fields */ }

Multi-collection geospatial engine.

Implementations

impl GeoEngine

pub fn new() -> Self

pub fn create_collection(&self, name: impl Into<String>) -> Result<(), GeoError>

pub fn drop_collection(&self, name: &str) -> Result<(), GeoError>

pub fn list_collections(&self) -> Vec<String>

pub fn collection_exists(&self, name: &str) -> bool

pub fn collection_stats(&self, name: &str) -> Option<CollectionStats>

pub fn upsert( &self, collection: &str, id: impl Into<String>, lat: f64, lon: f64, metadata: Value, ) -> Result<(), GeoError>

Upsert a feature. The collection is created on demand if it does not yet exist (the coordinate is validated first, so a bad write never creates an empty collection).

pub fn get( &self, collection: &str, id: &str, ) -> Result<Option<GeoFeature>, GeoError>

pub fn delete(&self, collection: &str, id: &str) -> Result<bool, GeoError>

pub fn within_radius( &self, collection: &str, lat: f64, lon: f64, radius_m: f64, filter: &Value, ) -> Result<Vec<GeoHit>, GeoError>

Features within radius_m of (lat, lon), nearest first.

pub fn within_bbox( &self, collection: &str, min_lat: f64, min_lon: f64, max_lat: f64, max_lon: f64, filter: &Value, ) -> Result<Vec<GeoHit>, GeoError>

Features inside a bounding box.

pub fn nearest( &self, collection: &str, lat: f64, lon: f64, k: usize, filter: &Value, ) -> Result<Vec<GeoHit>, GeoError>

The k nearest features to (lat, lon).

pub fn snapshot(&self) -> EngineSnapshot

pub fn load_snapshot(&self, snap: EngineSnapshot)

Trait Implementations

impl Default for GeoEngine

fn default() -> Self
