Struct Facility 

pub struct Facility<DataId, T: Send + Sync + Clone> { /* private fields */ }

A facility is a dataid and the center (or point in data) that correspond to a k medoid point.
The struture stores the data vector and point id which serve as a center, the sum of points weight attached to this point and the cost (distance between data points and center multiplied by point’s weight)

Implementations

impl<DataId: Debug + Clone, T: Send + Sync + Clone> Facility<DataId, T>

pub fn new(d_rank: DataId, center: &[T]) -> Self

creates a facility, around a point characteristics, As the point could be different from data as in kmean we do not set weight. So an explicit insertion with method insert must be done when creation facility is mean to also insert

pub fn get_position(&self) -> &Vec<T>

get a data point corresponding to the facility location

pub fn get_dataid(&self) -> DataId

get data rank this facility is centered on

pub fn get_weight(&self) -> f64

return sum of points’ weight dipatched to this center

pub fn get_cost(&self) -> f64

return cost carried by this facility $f$ i.e : $ cost(f) = \sum_{p \in f} w(p) * dist(p,f) $

pub fn log(&self)

dumps weight, cost and ratio
