Overview

Commands are a type of message that define the shape and contract data that is accepted for an attempt at performing a state change on a given aggregate. Essentially, they provide the api for interacting with your domain. Commands should have descriptive names capturing the change they are intended to make to the domain. For instance, ChangeUserEmail or AddComment. :reek:MissingSafeMethod { exclude: [ validate! ] }
