Required Methods

fn new(elements: &[Fq]) -> Self

fn get_element(&self, i: usize, j: usize) -> Fq

Get element[i,j]

fn set_element(&mut self, i: usize, j: usize, val: Fq)

Set element[i,j]

fn n_rows(&self) -> usize

Number of rows

fn n_cols(&self) -> usize

Number of columns

fn hadamard_product(&self, rhs: &Self) -> Result<Self, PoseidonParameterError>

where Self: Sized,

Compute Hadamard (element-wise) product

Provided Methods

fn iter_rows(&self) -> Chunks<'_, Fq>

Get rows

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
