Module domain_patterns::command

Command module holds traits relevant to marking commands, as well as command handler traits.

Traits

Command

Command is a simple marker trait for command structs. These are commands that are issued and handled by a command handler. They are things we can say "no" to.

Handles

Command handler will handle any generic message. This could be used in a 1:1 fashion, with only one handler per command, or you could implement this on a single handler that handles multiple messages, and lastly implement it on an enum that holds variants of those same commands. The enum implementation can simply match on self, and then call .handle which will use the incoming variant type to call the appropriate generic Handles implementation.
