Struct DfParams 

pub struct DfParams { /* private fields */ }

DF parameters (N̂, t, s₁, s₂) with optional fixed-base tables.

Implementations

impl DfParams

pub fn new(modulus: Modulus, t: Residue, s1: Residue, s2: Residue) -> Self

pub fn modulus(&self) -> &Modulus

pub fn t(&self) -> &Residue

pub fn s1(&self) -> &Residue

pub fn s2(&self) -> &Residue

pub fn with_tables(self, max_bits: u32, window: u32) -> Self

Builds comb tables for t, s₁, s₂ for exponents below 2^max_bits.

pub fn with_tables_sized(self, max_bits: [u32; 3], window: u32) -> Self

Like Self::with_tables with a separate exponent width per base: [t, s₁, s₂].

pub fn tables_size_bytes(&self) -> usize

Memory held by precomputed tables, in bytes.

pub fn commit_ct( &self, a: &SBig, b: &SBig, r: &SBig, bits: [u32; 3], ) -> Result<Residue>

s₁^{a} · s₂^{b} · t^{r} with secret exponents (prover side).

pub fn commit_vartime(&self, a: &SBig, b: &SBig, r: &SBig) -> Result<Residue>

s₁^{a} · s₂^{b} · t^{r} for public exponents (verifier side).

pub fn elements(&self) -> Vec<&Residue>

Residues of the parameters, e.g. for a transcript.
