Fields

rate: usize

The rate (in terms of number of field elements).

alpha: usize

Exponent used in S-boxes.

full_rounds: usize

Number of rounds in a full-round operation.

partial_rounds: usize

Number of rounds in a partial-round operation.

skip_matrices: usize

Number of matrices to skip when generating parameters using the Grain LFSR.

The matrices being skipped are those that do not satisfy all the desired properties. See the reference implementation for more detail.

Implementations

impl PoseidonDefaultParametersEntry

pub const fn new( rate: usize, alpha: usize, full_rounds: usize, partial_rounds: usize, skip_matrices: usize ) -> Self

Create an entry in PoseidonDefaultParameters.
