Function switchboard_solana::program_id::poseidon::hash

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

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

Examples

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

let input = [1u8; 32];

let result = hash(Parameters::Bn254X5, Endianness::BigEndian, &input).unwrap();
assert_eq!(
