Trait halo2_gadgets::poseidon::PoseidonInstructions

pub trait PoseidonInstructions<F: FieldExt, S: Spec<F, T, RATE>, const T: usize, const RATE: usize>: Chip<F> {
    type Word: Clone + Debug + From<AssignedCell<F, F>> + Into<AssignedCell<F, F>>;

    fn permute(
        &self,
        layouter: &mut impl Layouter<F>,
        initial_state: &[Self::Word; T]
    ) -> Result<[Self::Word; T], Error>;
}

The set of circuit instructions required to use the Poseidon permutation.

Required Associated Types

type Word: Clone + Debug + From<AssignedCell<F, F>> + Into<AssignedCell<F, F>>

Variable representing the word over which the Poseidon permutation operates.

Required Methods

fn permute(
    &self,
    layouter: &mut impl Layouter<F>,
    initial_state: &[Self::Word; T]
) -> Result<[Self::Word; T], Error>

Applies the Poseidon permutation to the given state.
