Implementations§

Source§

impl<S: PixSpec> SsaBuilder<S>

Source

pub fn new( full_commitment: PixGroup<S>, exit_secret_scalar: PixScalar<S>, num_polys: usize, ) -> Self

Source

pub fn num_polys(&self) -> usize

Number of polynomials this SSA is composed of.

Source

pub fn check_early_threshold(&mut self, threshold: f64) -> bool

Returns true once, when the number of received polynomial parts reaches ceil(threshold * num_polys) for the first time. Subsequent calls return false (idempotent guard — fires at most once per SSA lifecycle).

Source

pub fn add_recovered_ssa_part( &mut self, index: PolynomialIndex, sub_secret: PixScalar<S>, ) -> Result<Option<PixScalar<S>>, S::Pseudonym>
