Struct zkp_stark::TraceTable

pub struct TraceTable { /* fields omitted */ }

Methods

impl TraceTable

pub fn new(trace_length: usize, num_columns: usize) -> Self

Constructs a zero-initialized trace table of the given size.

pub fn num_rows(&self) -> usize

pub fn num_columns(&self) -> usize

pub fn generator(&self) -> FieldElement

pub fn iter_row(&self, i: usize) -> impl Iterator<Item = &FieldElement>

pub fn iter_column(&self, j: usize) -> impl Iterator<Item = &FieldElement>

pub fn column_to_mmapvec(&self, j: usize) -> MmapVec<FieldElement>

Extract the j-th column as a vector

It allocates a potentially large new vector. Where possible, use the index accessors or the column iterator instead. It is unfortunately not possible to get a slice of a column (since the representation is row first.)

pub fn interpolate(&self) -> Vec<DensePolynomial>

Trait Implementations

impl Index<(usize, usize)> for TraceTable

Returns a field

type Output = FieldElement

fn index(&self, (i, j): (usize, usize)) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Index<usize> for TraceTable

Returns a row as a slice

type Output = [FieldElement]

The returned type after indexing.

fn index(&self, i: usize) -> &[FieldElement]

Performs the indexing (container[index]) operation.

impl IndexMut<(usize, usize)> for TraceTable

Returns a mutable field

fn index_mut(&mut self, (i, j): (usize, usize)) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl IndexMut<usize> for TraceTable

Returns a mutable row as a slice

fn index_mut(&mut self, i: usize) -> &mut [FieldElement]

impl Debug for TraceTable

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
