func (Context) IsEmpty

func (ctx Context) IsEmpty() bool

IsEmpty only check if task queue set.

type ContinueAsNew

type ContinueAsNew struct {
	// Result defines workflow execution result.

}

ContinueAsNew restarts workflow with new running instance.

ActivityParams maps activity command to activity params.

type ExecuteChildWorkflow

type ExecuteChildWorkflow struct {
	// Name defines workflow name.
	Name string `json:"name"`
	// Options to run activity.
	Options bindings.WorkflowOptions `json:"options,omitempty"`
}

ExecuteChildWorkflow executes child workflow.

func (ExecuteChildWorkflow) WorkflowParams

func (cmd ExecuteChildWorkflow) WorkflowParams(env bindings.WorkflowEnvironment, payloads *commonpb.Payloads, header *commonpb.Header) bindings.ExecuteWorkflowParams

WorkflowParams maps workflow command to workflow params.

type ExecuteLocalActivity

type ExecuteLocalActivity struct {
	// Name defines activity name.
	Name string `json:"name"`
	// Options to run activity.
	Options ExecuteLocalActivityOptions `json:"options,omitempty"`

ExecuteLocalActivity command by workflow worker.

func (ExecuteLocalActivity) LocalActivityParams

func (cmd ExecuteLocalActivity) LocalActivityParams(env bindings.WorkflowEnvironment, fn any, payloads *commonpb.Payloads, header *commonpb.Header) bindings.ExecuteLocalActivityParams

LocalActivityParams maps activity command to activity params.

type ExecuteLocalActivityOptions

type ExecuteLocalActivityOptions struct {
	ScheduleToCloseTimeout time.Duration
	StartToCloseTimeout    time.Duration
	RetryPolicy            *commonpb.RetryPolicy
}

ExecuteLocalActivityOptions .. since we use proto everywhere we need to convert Activity options (proto) to non-proto LA options

type GetChildWorkflowExecution

type GetChildWorkflowExecution struct {
	// ID of child workflow command.
	ID uint64 `json:"id"`
}

GetChildWorkflowExecution returns the WorkflowID and RunId of child workflow.

type GetStackTrace

type GetStackTrace struct {
	// RunID workflow run id.
	RunID string `json:"runId"`
}

GetStackTrace asks worker to offload workflow from memory.

type GetVersion

type GetVersion struct {
	ChangeID     string `json:"changeID"`
	MinSupported int    `json:"minSupported"`
	MaxSupported int    `json:"maxSupported"`
}

GetVersion requests version marker.

type GetWorkerInfo

type GetWorkerInfo struct {
	RRVersion string `json:"rr_version"`
}

GetWorkerInfo reads worker information.

type InvokeActivity

type InvokeActivity struct {
	// Name defines activity name.
	Name string `json:"name"`

	// Info contains execution context.
	Info activity.Info `json:"info"`

	// HeartbeatDetails indicates that the payload also contains last heartbeat details.
	HeartbeatDetails int `json:"heartbeatDetails,omitempty"`
