setup.go

// Package setup bridges the root workflow package with the handlers and
// module packages to register default workflow handlers and triggers.
// It exists to break the import cycle that would occur if the root package
// directly imported handlers (which has test files that import the root package).
//
// Typical usage is to blank-import this package so that its init function
// registers the default handler and trigger factories with the workflow
// engine, and then build an engine using the workflow package:
//
//	import (
//		"github.com/GoCodeAlone/workflow"
//		_ "github.com/GoCodeAlone/workflow/setup"
//	)
//
//	engine, err := workflow.NewEngineBuilder().
//		WithAllDefaults().
//		Build()
