Access to individual points and trajectories.

Required Methods

fn trajectory(&self, entity_id: u64, filter: TemporalFilter) -> Vec<(i64, u32)>

Retrieve trajectory for an entity: (timestamp, node_id) pairs.

fn vector(&self, node_id: u32) -> Vec<f32>

Get the vector for a node. Returns owned vec for thread safety.

fn entity_id(&self, node_id: u32) -> u64

Get the entity_id for a node.

fn timestamp(&self, node_id: u32) -> i64

Get the timestamp for a node.

fn len(&self) -> usize

Number of points in the index.

Provided Methods

fn is_empty(&self) -> bool

Whether the index is empty.
