function eip712HashType(string calldata typeNameOrDefinition) external pure returns (bytes32 typeHash);
function eip712HashType(string calldata bindingsPath, string calldata typeName) external pure returns (bytes32 typeHash);
function eip712HashStruct(string calldata typeNameOrDefinition, bytes calldata abiEncodedData) external pure returns (bytes32 typeHash);
function eip712HashStruct(string calldata bindingsPath, string calldata typeName, bytes calldata abiEncodedData) external pure returns (bytes32 typeHash);
function eip712HashTypedData(string calldata jsonData) external pure returns (bytes32 digest);
