Functions

func CreateDeploymentScript

func CreateDeploymentScript(avm []byte, manif *manifest.Manifest) ([]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.

Types

type BlockFilter

type BlockFilter struct {
	Primary int `json:"primary"`
}

BlockFilter is a wrapper structure for block event filter. The only allowed filter is primary index.

type ExecutionFilter

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

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.

type Param

type Param struct {
	Type  paramType
	Value interface{}
}

Param represents a param either passed to the server or to send to a server using the client.

func (*Param) GetArray

func (p *Param) GetArray() ([]Param, error)

GetArray returns a slice of Params stored in the parameter.

func (*Param) GetBoolean

func (p *Param) GetBoolean() bool

GetBoolean returns boolean value of the parameter.

func (*Param) GetBytesBase64

func (p *Param) GetBytesBase64() ([]byte, error)

GetBytesBase64 returns []byte value of the parameter if it is a base64-encoded string.

func (*Param) GetBytesHex

func (p *Param) GetBytesHex() ([]byte, error)

GetBytesHex returns []byte value of the parameter if it is a hex-encoded string.

func (Param) GetCosigner

func (p Param) GetCosigner() (transaction.Cosigner, error)

GetCosigner returns transaction.Cosigner value of the parameter.

func (Param) GetCosigners

func (p Param) GetCosigners() ([]transaction.Cosigner, error)

GetCosigners returns a slice of transaction.Cosigner with global scope from array of Uint160 or array of serialized transaction.Cosigner stored in the parameter.

func (*Param) GetFuncParam

func (p *Param) GetFuncParam() (FuncParam, error)

GetFuncParam returns current parameter as a function call parameter.

func (*Param) GetInt

func (p *Param) GetInt() (int, error)

GetInt returns int value of te parameter.

func (*Param) GetString

func (p *Param) GetString() (string, error)

GetString returns string value of the parameter.

func (*Param) GetUint160FromAddress

func (p *Param) GetUint160FromAddress() (util.Uint160, error)

GetUint160FromAddress returns Uint160 value of the parameter that was supplied as an address.

func (*Param) GetUint160FromHex

func (p *Param) GetUint160FromHex() (util.Uint160, error)

GetUint160FromHex returns Uint160 value of the parameter encoded in hex.

func (*Param) GetUint256

func (p *Param) GetUint256() (util.Uint256, error)

GetUint256 returns Uint256 value of the parameter.

func (Param) String

func (p Param) String() string

func (*Param) UnmarshalJSON

func (p *Param) UnmarshalJSON(data []byte) error

UnmarshalJSON implements json.Unmarshaler interface.

type Params

type Params []Param

Params represents the JSON-RPC params.

func (Params) Value

func (p Params) Value(index int) *Param

Value returns the param struct for the given index if it exists.

func (Params) ValueWithType

func (p Params) ValueWithType(index int, valType paramType) *Param

ValueWithType returns the param struct at the given index if it exists and matches the given type.

type Raw

type Raw struct {
	JSONRPC   string        `json:"jsonrpc"`
	Method    string        `json:"method"`
	RawParams []interface{} `json:"params"`
	ID        int           `json:"id"`
}

Raw represents JSON-RPC request.

type RawParams

type RawParams struct {
	Values []interface{}
}
