Function hashv

pub fn hashv(
    parameters: Parameters,
    endianness: Endianness,
    vals: &[&[u8]],
) -> Result<PoseidonHash, PoseidonSyscallError>

Return a Poseidon hash for the given data with the given elliptic curve and endianness.

Examples

use solana_program::poseidon::{hashv, Endianness, Parameters};

let input1 = [1u8; 32];
let input2 = [2u8; 32];

let hash = hashv(Parameters::Bn254X5, Endianness::BigEndian, &[&input1, &input2]).unwrap();
assert_eq!(
    hash.to_bytes(),
    [
        13, 84, 225, 147, 143, 138, 140, 28, 125, 235, 94, 3, 85, 242, 99, 25, 32, 123,
