Types

type Config

type Config struct {
	Name        string `json:"name"`
	Type        string `json:"type"`
	Description string `json:"description"`

	StopEngineOnError bool   `json:"stopEngineOnError,omitempty"`
	RunnerType        string `json:"runnerType,omitempty"`

	Imports        []string                          `json:"imports,omitempty"`
