Module pptr::message

Defines message types and communication primitives for the puppet system.

• Message: A marker trait for types that can be used as messages.
• Envelope: A trait for message envelopes that can be handled by puppets.
• Packet: A struct representing a message packet with an optional reply address.
• ServicePacket: A struct representing a packet sent to a service for processing.
• Postman: A struct for sending messages to puppets.
• ServicePostman: A struct for sending commands to services.
