Types

type ChainResult

type ChainResult struct {
	//success bool
	TxHash []byte
}

type Resolver

type Resolver interface {
	// GetCid Resolve cid from  uri
	GetCid(aufsUri string) []byte

	// GetNodesFromCid  Get source nodes of specified cid
	GetNodesFromCid([]byte) []boson.Address

	// GetSourceNodes  Short hand function, get storage nodes from uri
	GetSourceNodes(aufsUri string) []boson.Address

	// OnStoreMatched Notification when new data req matched
	OnStoreMatched(cid boson.Address, dataLen uint64, salt uint64, address boson.Address)

	// DataStoreFinished when data retrieved and saved, use this function to report onchain
	DataStoreFinished(cid boson.Address, dataLen uint64, salt uint64, proof []byte, resCh chan ChainResult)
}

type Traffic

type Traffic interface {

	// 	TransferredAddress opts todo
	TransferredAddress(address common.Address) ([]common.Address, error)

	RetrievedAddress(address common.Address) ([]common.Address, error)

	BalanceOf(account common.Address) (*big.Int, error)

	RetrievedTotal(address common.Address) (*big.Int, error)

	TransferredTotal(address common.Address) (*big.Int, error)

	TransAmount(beneficiary, recipient common.Address) (*big.Int, error)

	CashChequeBeneficiary(beneficiary, recipient common.Address, cumulativePayout *big.Int, signature []byte) (*types.Transaction, error)
}

type Transaction

type Transaction interface {
	// Send creates a transaction based on the request and sends it.
	Send(ctx context.Context, request *TxRequest) (txHash common.Hash, err error)
	// Call simulate a transaction based on the request.
	Call(ctx context.Context, request *TxRequest) (result []byte, err error)
	// WaitForReceipt waits until either the transaction with the given hash has been mined or the context is cancelled.
	WaitForReceipt(ctx context.Context, txHash common.Hash) (receipt *types.Receipt, err error)
}

Service is the service to send transactions. It takes care of gas price, gas limit and nonce management.

type TxRequest

type TxRequest struct {
	To       *common.Address // recipient of the transaction
	Data     []byte          // transaction data
	GasPrice *big.Int        // gas price or nil if suggested gas price should be used
	GasLimit uint64          // gas limit or 0 if it should be estimated
	Value    *big.Int        // amount of wei to send
}

TxRequest describes a request for a transaction that can be executed.
