Struct prio::dp::distributions::DiscreteGaussian

source · 
pub struct DiscreteGaussian { /* private fields */ }
Available on crate feature experimental only.
Expand description

Samples BigInt numbers according to the discrete Gaussian distribution with mean zero. The distribution is defined over the integers, represented by arbitrary-precision integers. The sampling procedure follows [CKS20].
