Fields§
§param_file_path: PathBuf
The parameter file we’re reading from.
param_file: File
The file descriptor we have mmaped.
params: Mmap
The actual mmap.
vk: VerifyingKey<E>
This is always loaded (i.e. not lazily loaded).
pvk: PreparedVerifyingKey<E>
§h: Vec<Range<usize>>
Elements of the form ((tau^i * t(tau)) / delta) for i between 0 and m-2 inclusive. Never contains points at infinity.
l: Vec<Range<usize>>
Elements of the form (beta * u_i(tau) + alpha v_i(tau) + w_i(tau)) / delta for all auxiliary inputs. Variables can never be unconstrained, so this never contains points at infinity.
a: Vec<Range<usize>>
QAP “A” polynomials evaluated at tau in the Lagrange basis. Never contains points at infinity: polynomials that evaluate to zero are omitted from the CRS and the prover can deterministically skip their evaluation.
b_g1: Vec<Range<usize>>
QAP “B” polynomials evaluated at tau in the Lagrange basis. Needed in G1 and G2 for C/B queries, respectively. Never contains points at infinity for the same reason as the “A” polynomials.
b_g2: Vec<Range<usize>>
§checked: bool
