Struct FeatureStore 

pub struct FeatureStore { /* private fields */ }

Persistent bbox store backed by redb.

For incremental tile updates, we only need to know WHICH tiles are affected by a change. We store the bounding box of each feature by OSM ID. The full feature data (geometry, tags) lives in the PMTiles output and is regenerated from the PBF + changes.

Implementations

impl FeatureStore

pub fn open(path: &Path) -> OsmicResult<Self>

Open or create a feature store at the given path.

pub fn upsert(&self, id: i64, bbox: &BBox) -> OsmicResult<Option<BBox>>

Store a feature’s bounding box. Returns the old bbox if it existed.

pub fn delete(&self, id: i64) -> OsmicResult<Option<BBox>>

Delete a feature’s bbox by ID. Returns the old bbox if it existed.

pub fn get_bbox(&self, id: i64) -> OsmicResult<Option<BBox>>

Get a stored bbox by ID.

pub fn len(&self) -> OsmicResult<u64>

Count of features in the store.

pub fn is_empty(&self) -> OsmicResult<bool>
