Implementations

impl SortAttributes

pub fn new(opts: Arc<SortAttributesOptions>) -> Self

Creates new attributes with limited history

Parameters

• opts - options

Trait Implementations

impl Clone for SortAttributes

fn clone(&self) -> SortAttributes

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SortAttributes

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SortAttributes

fn default() -> Self

Returns the “default value” for a type.

impl LookupRequest<SortAttributes, Universal2DBox> for SortLookup

fn lookup( &self, attributes: &SortAttributes, _observations: &ObservationsDb<Universal2DBox>, _merge_history: &[u64], ) -> bool

impl ObservationMetric<SortAttributes, Universal2DBox> for SortMetric

fn metric( &self, mq: &MetricQuery<'_, SortAttributes, Universal2DBox>, ) -> MetricOutput<f32>

calculates the distance between two features.

fn optimize( &mut self, _feature_class: u64, _merge_history: &[u64], attrs: &mut SortAttributes, features: &mut Vec<Observation<Universal2DBox>>, _prev_length: usize, _is_merge: bool, ) -> Result<()>

the method is used every time, when a new observation is added to the feature storage as well as when two tracks are merged.

fn postprocess_distances( &self, unfiltered: Vec<ObservationMetricOk<Universal2DBox>>, ) -> Vec<ObservationMetricOk<Universal2DBox>>

The postprocessing is run just before the executor returns calculated distances.

impl TrackAttributes<SortAttributes, Universal2DBox> for SortAttributes

type Update = SortAttributesUpdate

type Lookup = SortLookup

fn compatible(&self, other: &SortAttributes) -> bool

The method is used to evaluate attributes of two tracks to determine whether tracks are compatible for distance calculation. When the attributes are compatible, the method returns true.

fn merge(&mut self, other: &SortAttributes) -> Result<()>

When the tracks are merged, their attributes are merged as well. The method defines the approach to merge attributes.

fn baked( &self, _observations: &ObservationsDb<Universal2DBox>, ) -> Result<TrackStatus>

The method is used by storage to determine when track is ready/not ready/wasted. Look at TrackStatus.

impl TrackAttributesKalmanPrediction for SortAttributes

fn get_state(&self) -> Option<KalmanState<{ DIM_2D_BOX_X2 }>>

fn set_state(&mut self, state: KalmanState<{ DIM_2D_BOX_X2 }>)

impl TrackAttributesUpdate<SortAttributes> for SortAttributesUpdate

fn apply(&self, attrs: &mut SortAttributes) -> Result<()>

Method is used to update track attributes from update structure.
