// The struct consists of name of the protocol adapter,
// action type, array of token amounts,
// and some additional data (depends on the protocol).
struct Action {
    bytes32 protocolAdapterName;
    ActionType actionType;
    TokenAmount[] tokenAmounts;
    bytes data;
}

// The struct consists of token address
// and its absolute amount.
struct AbsoluteTokenAmount {

    uint256 amount;
}

enum ActionType { None, Deposit, Withdraw }

enum AmountType { None, Relative, Absolute }
