Types

type AutoscalerError

type AutoscalerError interface {
	// Error implements golang error interface
	Error() string

	// Type returns the type of AutoscalerError
	Type() AutoscalerErrorType

	// AddPrefix adds a prefix to error message.
	// Returns the error it's called for convenient inline use.
	// Example:
	// if err := DoSomething(myObject); err != nil {
	//	return err.AddPrefix("can't do something with %v: ", myObject)
	// }
	AddPrefix(msg string, args ...interface{}) AutoscalerError
}

AutoscalerError contains information about Autoscaler errors

func NewAutoscalerError

func NewAutoscalerError(errorType AutoscalerErrorType, msg string, args ...interface{}) AutoscalerError

NewAutoscalerError returns new autoscaler error with a message constructed from format string

func ToAutoscalerError

func ToAutoscalerError(defaultType AutoscalerErrorType, err error) AutoscalerError

ToAutoscalerError converts an error to AutoscalerError with given type, unless it already is an AutoscalerError (in which case it's not modified).

type AutoscalerErrorType

type AutoscalerErrorType string

AutoscalerErrorType describes a high-level category of a given error
