type MyStep struct{} func (s *MyStep) Run(state multistep.StateBag) multistep.StepAction { // Get the value from the previous step, if present value, ok := state.GetOk("my_key") if !ok { // If the key isn't present, set a default value value = "default_value" } fmt.Println("Value is:", value) // Store a new value for the next step state.Put("my_key", "new_value") return multistep.ActionContinue }In this example, the `MyStep` type implements the `multistep.Step` interface and uses the `StateBag` passed to it in the `Run` method. It first checks if a value for "my_key" is already present in the `StateBag`, and sets a default value if not. It then prints out the current value of "my_key". Finally, it stores a new value for "my_key" that will be passed to the next step. Another example of using `StateBag` could involve passing information between steps in a workflow, such as user input or configuration options. The `StateBag` type allows for a flexible and convenient way to organize and maintain this information throughout the workflow. Overall, the `github.com/mitchellh/multistep` package is a useful library for organizing multi-step processes in Go. Its `StateBag` type allows for easy data sharing between steps and provides a flexible interface for developing complex workflows.
