Functions

func CodeHash

func CodeHash(code []byte) (h common.Hash)

func Hash

func Hash(inpBI []*big.Int, width int) (*big.Int, error)

for short, use size of inpBI as cap

func HashFixed

func HashFixed(inpBI []*big.Int) (*big.Int, error)

Hash computes the Poseidon hash for the given fixed-size inputs, select specs automatically from the size, no capacity flag is applied

func HashWithCap

func HashWithCap(inpBI []*big.Int, width int, nBytes int64) (*big.Int, error)

Hash using possible sponge specs specified by width (rate from 1 to 15), the size of input is applied as capacity (notice we do not include width in the capacity )
