Shared geometry and bounds for (R_q) instantiations used with ML-DSA.

Required Associated Constants

const N: usize

Polynomial degree n.

const Q: i32

Modulus q.

const ROWS_IN_A: usize

Matrix rows k.

const COLUMNS_IN_A: usize

Matrix columns l.

const TAU: usize

Hamming weight τ of the challenge polynomial.

const GAMMA1_EXPONENT: usize

γ₁ = 2^{γ₁_exp}.

const GAMMA2: i32

γ₂ = ⌊(q-1)/88⌋ (ML-DSA-44) or ⌊(q-1)/32⌋ (65/87).

const ETA: i32

η (centered binomial / uniform width parameter as an integer bound).

const BETA: i32

β = τ · η.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
