Implementations§

Source§

impl DifferentialPrivacy

Source

pub fn new() -> Self

Source

pub fn initialize(&mut self) -> Result<(), StatisticalError>

Source

pub fn noise_mechanisms(&self) -> &[NoiseMechanism]

Returns the list of noise mechanisms available to this DP engine.

Source

pub fn add_noise_mechanism(&mut self, mechanism: NoiseMechanism)

Register an additional noise mechanism if not already present.

Source

pub fn supports_noise_mechanism(&self, mechanism: &NoiseMechanism) -> bool

Returns true when the given noise mechanism is registered.

Source

pub fn privacy_accountant(&self) -> &PrivacyAccountant

Returns a reference to the privacy accountant tracking epsilon/delta spend.

Source

pub fn privacy_accountant_mut(&mut self) -> &mut PrivacyAccountant

Returns a mutable reference to the privacy accountant.

Source

pub fn spend_budget( &mut self, epsilon: f64, delta: f64, ) -> Result<(), StatisticalError>

Spend epsilon/delta from the privacy budget, recording the consumption in the accountant. Returns Err when the budget is insufficient.
