Struct opendp::core::PrivacyRelation

pub struct PrivacyRelation<MI: Metric, MO: Measure> {
    pub relation: Rc<dyn Fn(&MI::Distance, &MO::Distance) -> Fallible<bool>>,
    pub backward_map: Option<Rc<dyn Fn(&MO::Distance) -> Fallible<Box<MI::Distance>>>>,
}

A boolean relation evaluating the privacy of a Measurement.

A PrivacyRelation is implemented as a function that takes an input Metric::Distance and output Measure::Distance, and returns a boolean indicating if the relation holds.

Fields

relation: Rc<dyn Fn(&MI::Distance, &MO::Distance) -> Fallible<bool>>

backward_map: Option<Rc<dyn Fn(&MO::Distance) -> Fallible<Box<MI::Distance>>>>
