Structs, enums, and constants
struct Action {bytes32 protocolAdapterName;ActionType actionType;TokenAmount[] tokenAmounts;bytes data;}
protocolAdapterName — protocol adapter name converted to hex
actionType — type of action to be executed
tokenAmounts — array of tokens' addresses to be deposited/withdrawn
data — additional data required for the action (depends on actionType, adapterIndex, and protocolName).
Parameter of type

struct TokenAmount {address token;uint256 amount;AmountType amountType;}
token — address of token used for input
amount — token amount for input (absolute or relative)
absolute amount is passed in wei
relative amount is passed in share (e.g.
0.5for 50%) multiplied by1e18(eventually, it's5e17for 50%)
amountType — indicator whether amount is absolute or relative
struct AbsoluteTokenAmount {address token;uint256 amount;}
token — address of token
amount — token amount (always absolute)
struct Fee {uint256 share;address beneficiary;}
share — fee share scaled by 1e18
beneficiry — receiver of the fee
ACTION_DEPOSIT = 1 // buy uni tokens, buy token sets, exchange with fixed inputACTION_WITHDRAW = 2 // sell uni tokens, sell token sets, exchange with fixed output
