Overview ¶

The validator plugin generates a Validate method for each message. By default, if none of the message's fields are annotated with the gogo validator annotation, it returns a nil. In case some of the fields are annotated, the Validate function returns nil upon sucessful validation, or an error describing why the validation failed. The Validate method is called recursively for all submessage of the message.
