Functions

func PrintCancelOrderLog 

func PrintCancelOrderLog(log *contractsinterfaces.ExchangeLogCancelOrder) string

func PrintErrorLog 

func PrintErrorLog(log *contractsinterfaces.ExchangeLogError) string

func PrintTradeLog 

func PrintTradeLog(log *contractsinterfaces.ExchangeLogTrade) string

Types

type Exchange 

type Exchange struct {
	Address       common.Address
	WalletService interfaces.WalletService
	Interface     *contractsinterfaces.Exchange
	Client        ethereumClientInterface
}

Exchange is an augmented interface to the Exchange.sol smart-contract. It uses the smart-contract bindings generated with abigen and adds additional functionality and simplifications to these bindings. Address is the Ethereum address of the exchange contract Contract is the original abigen bindings CallOptions are options for making read calls to the connected backend TxOptions are options for making write txs to the connected backend

func NewExchange 

func NewExchange(
	w interfaces.WalletService,
	address common.Address,
	backend ethereumClientInterface,
) (*Exchange, error)

Returns a new exchange interface for a given wallet, contract address and connected backend. The exchange contract need to be already deployed at the given address. The given wallet will be used by default when sending transactions with this object.

func (*Exchange) CallBatchTrades 

func (e *Exchange) CallBatchTrades(matches *types.Matches, call *ethereum.CallMsg) (uint64, error)

func (*Exchange) CallTrade 

func (e *Exchange) CallTrade(match *types.Matches, call *ethereum.CallMsg) (uint64, error)

func (*Exchange) DefaultTxOptions 

func (e *Exchange) DefaultTxOptions() (*bind.TransactOpts, error)

func (*Exchange) ExecuteBatchTrades 

func (e *Exchange) ExecuteBatchTrades(matches *types.Matches, txOpts *bind.TransactOpts) (*eth.Transaction, error)

func (*Exchange) FeeAccount 

func (e *Exchange) FeeAccount() (common.Address, error)

FeeAccount is the Ethereum towards the exchange trading fees are sent

func (*Exchange) GetAddress 

func (e *Exchange) GetAddress() common.Address

func (*Exchange) GetErrorEvents 

func (e *Exchange) GetErrorEvents(logs chan *contractsinterfaces.ExchangeLogError) error

func (*Exchange) GetTrades 

func (e *Exchange) GetTrades(logs chan *contractsinterfaces.ExchangeLogTrade) error

func (*Exchange) GetTxCallOptions 

func (e *Exchange) GetTxCallOptions() *bind.CallOpts

func (*Exchange) ListenToBatchTrades 

func (e *Exchange) ListenToBatchTrades() (chan *contractsinterfaces.ExchangeLogBatchTrades, error)

func (*Exchange) ListenToErrors 

func (e *Exchange) ListenToErrors() (chan *contractsinterfaces.ExchangeLogError, error)

ListenToErrorEvents returns a channel that receives errors logs (events) from the exchange smart contract. The error IDs correspond to the following codes: 1. MAKER_INSUFFICIENT_BALANCE, 2. TAKER_INSUFFICIENT_BALANCE, 3. WITHDRAW_INSUFFICIENT_BALANCE, 4. WITHDRAW_FEE_TO_HIGH, 5. ORDER_EXPIRED, 6. WITHDRAW_ALREADY_COMPLETED, 7. TRADE_ALREADY_COMPLETED, 8. TRADE_AMOUNT_TOO_BIG, 9. SIGNATURE_INVALID, 10. MAKER_SIGNATURE_INVALID, 11. TAKER_SIGNATURE_INVALID

func (*Exchange) ListenToTrades 

func (e *Exchange) ListenToTrades() (chan *contractsinterfaces.ExchangeLogTrade, error)

ListenToTrades returns a channel that receivs trade logs (events) from the underlying exchange smart contract

func (*Exchange) Operator 

func (e *Exchange) Operator(a common.Address) (bool, error)

func (*Exchange) PrintErrors 

func (e *Exchange) PrintErrors() error

func (*Exchange) PrintTrades 

func (e *Exchange) PrintTrades() error

func (*Exchange) SetFeeAccount 

func (e *Exchange) SetFeeAccount(a common.Address, txOpts *bind.TransactOpts) (*eth.Transaction, error)

SetFeeAccount sets the fee account of the exchange contract. The fee account receives the trading fees whenever a trade is settled.

func (*Exchange) SetOperator 

func (e *Exchange) SetOperator(a common.Address, isOperator bool, txOpts *bind.TransactOpts) (*eth.Transaction, error)

SetOperator updates the operator settings of the given address. Only addresses with an operator access can execute Withdraw and Trade transactions to the Exchange smart contract

func (*Exchange) Trade 

func (e *Exchange) Trade(match *types.Matches, txOpts *bind.TransactOpts) (*eth.Transaction, error)

Trade executes a settlements transaction. The order and trade payloads need to be signed respectively by the Maker and the Taker of the trade. Only the operator account can send a Trade function to the Exchange smart contract.
