Struct Message 

pub struct Message {
    pub id: String,
    pub topic: String,
    pub payload: Vec<u8>,
    pub sender: String,
    pub metadata: HashMap<String, String>,
    pub created_at: i64,
}

A message for inter-agent communication.

Messages carry binary payloads between agents in a mesh.

Example

use ceylon_core::Message;

// Create a message
let msg = Message::new("greeting", b"Hello!".to_vec(), "sender-agent");

// Access message properties
println!("Topic: {}", msg.topic);
println!("From: {}", msg.sender);

Fields

id: String

Unique message identifier (auto-generated UUID).

topic: String

Message topic/type for routing or categorization.

payload: Vec<u8>

Binary payload data.

sender: String

Name of the sending agent.

metadata: HashMap<String, String>

Arbitrary metadata key-value pairs.

created_at: i64

Creation timestamp in microseconds since epoch.
