Functions

func AddInputsAndUnspentsToTx 

func AddInputsAndUnspentsToTx(tx *transaction.Transaction, addr string, assetID util.Uint256, amount util.Fixed8, balancer BalanceGetter) error

AddInputsAndUnspentsToTx adds inputs needed to transaction and one output with change.

func CreateDeploymentScript 

func CreateDeploymentScript(avm []byte, contract *smartcontract.ContractDetails) ([]byte, error)

CreateDeploymentScript returns a script that deploys given smart contract with its metadata.

func CreateFunctionInvocationScript 

func CreateFunctionInvocationScript(contract util.Uint160, params Params) ([]byte, error)

CreateFunctionInvocationScript creates a script to invoke given contract with given parameters.

func CreateInvocationScript 

func CreateInvocationScript(contract util.Uint160, funcParams []Param) ([]byte, error)

CreateInvocationScript creates a script to invoke given contract with given parameters. It differs from CreateFunctionInvocationScript in that it expects one array of FuncParams and expands it onto the stack as independent elements.

func CreateRawContractTransaction 

func CreateRawContractTransaction(params ContractTxParams) (*transaction.Transaction, error)

CreateRawContractTransaction returns contract-type Transaction built from specified parameters.

func DetailsToSCProperties 

func DetailsToSCProperties(contract *smartcontract.ContractDetails) smartcontract.PropertyState

DetailsToSCProperties extract the fields needed from ContractDetails and converts them to smartcontract.PropertyState.

Types

type BalanceGetter 

type BalanceGetter interface {
	// 		parameters
	// address: 	base58-encoded address assets would be transferred from
	// assetID: 	asset identifier
	// amount: 		an asset amount to spend
	// 		return values
	// inputs: 		UTXO's for the preparing transaction
	// total: 		summarized asset amount from all the `inputs`
	// error: 		error would be considered in the caller function
	CalculateInputs(address string, assetID util.Uint256, amount util.Fixed8) (inputs []transaction.Input, total util.Fixed8, err error)
}

BalanceGetter is an interface supporting CalculateInputs() method.

type ContractTxParams 

type ContractTxParams struct {
	AssetID util.Uint256
	Address string
	Value   util.Fixed8
	WIF     keys.WIF // a WIF to send the transaction
	// since there are many ways to provide unspents,
	// transaction composer stays agnostic to that how
	// unspents was got;
	Balancer BalanceGetter
}

ContractTxParams contains parameters for tx to transfer assets. It includes (*Client).TransferAsset call params and utility data.

type ExecutionFilter added in v0.75.0 

type ExecutionFilter struct {
	State string `json:"state"`
}

ExecutionFilter is a wrapper structure used for transaction execution events. It allows to choose failing or successful transactions based on their VM state.

type FuncParam 

type FuncParam struct {
	Type  smartcontract.ParamType `json:"type"`
	Value Param                   `json:"value"`
}

FuncParam represents a function argument parameter used in the invokefunction RPC method.

type In 

type In struct {
	JSONRPC   string          `json:"jsonrpc"`
	Method    string          `json:"method"`
	RawParams json.RawMessage `json:"params,omitempty"`
	RawID     json.RawMessage `json:"id,omitempty"`
}

In represents a standard JSON-RPC 2.0 request: http://www.jsonrpc.org/specification#request_object. It's used in server to represent incoming queries.

func NewIn 

func NewIn() *In

NewIn creates a new Request struct.

func (*In) DecodeData 

func (r *In) DecodeData(data io.ReadCloser) error

DecodeData decodes the given reader into the the request struct.

func (*In) Params 

func (r *In) Params() (*Params, error)

Params takes a slice of any type and attempts to bind the params to it.

type NotificationFilter added in v0.75.0 

type NotificationFilter struct {
	Contract util.Uint160 `json:"contract"`
}

NotificationFilter is a wrapper structure representing filter used for notifications generated during transaction execution. Notifications can only be filtered by contract hash.
