Types

type CreateRequest

type CreateRequest struct {
	Type string                 // the type of request being made
	Args map[string]interface{} // the arguments for the request
	User string                 // the user making the request
}

CreateRequest represents the payload to create and start a new request.

type Error

type Error struct {
	Message    string `json:"message"`    // human-readable and loggable error message
	RequestId  string `json:"requestId"`  // entity ID that caused error, if any
	HTTPStatus int    `json:"httpStatus"` // HTTP status code
}

Error is the standard response for all handled errors. Client errors (HTTP 400 codes) and internal errors (HTTP 500 codes) are returned as an Error, if handled. If not handled (API crash, panic, etc.), Spin Cycle returns an HTTP 500 code and the response data is undefined; the client should print any response data as a string.

func NewError

func NewError(msgFmt string, msgArgs ...interface{}) Error

func (Error) Error

func (e Error) Error() string

func (Error) String

func (e Error) String() string

type FinishRequest

type FinishRequest struct {

	FinishedAt   time.Time `json:"finishedAt"`   // when the Job Runner finished the request
	FinishedJobs uint      `json:"finishedJobs"` // number of jobs that ran and finished with state = STATE_COMPLETE
}

FinishRequest represents the payload to tell the RM that a request has finished.

	RetryWait         string                 `json:"retryWait,omitempty"`         // wait between tries (duration string: "N{ms|s|m|h}", default: 0s)
	SequenceId        string                 `json:"sequenceId"`                  // Job.Id of first job in sequence
	SequenceRetry     uint                   `json:"sequenceRetry"`               // retry sequence N times if first run fails. Only set for first job in sequence.
