Struct b2dp::mechanisms::exponential::ExponentialOptions

pub struct ExponentialOptions {
    pub min_retries: u32,
    pub optimized_sample: bool,
    pub empirical_precision: bool,
}

The exponential mechanism optional parameters.

Fields

min_retries: u32

The minimum number of retries for timing channel prevention default: 1 Minimum retries helps to mitigate timing channels in optimized sampling. The higher the number of retries, the less likely it is for an adversary to observe useful timing information.

optimized_sample: bool

Whether to optimize sampling default: false Optimized sampling exacerbates timing channels, and it's not recommended for use in un-trusted settings.

empirical_precision: bool

Whether to use empirical precision default: false Determination of safe precision given utility bounds and outcome set size limits can be done analytically or empirically. Both are independent of the dataset. Using empirical_precision = true determines the required precision via a set of test calculations. The timing overhead of these calculations is proportional to the outcome set size, and the overhead may outweigh any reduction in required precision.
