Enum MessageTarget 

#[non_exhaustive]
pub enum MessageTarget {
    Process(Pid),
    Topic(String),
    Broadcast,
    Service(String),
    ServiceMethod {
        service: String,
        method: String,
    },
    Kernel,
    RemoteNode {
        node_id: String,
        target: Box<MessageTarget>,
    },
}

Target for a kernel message.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Process(Pid)

Send to a specific process by PID.

Topic(String)

Publish to a named topic (all subscribers receive).

Broadcast

Broadcast to all processes.

Service(String)

Send to a named service (routed via ServiceRegistry).

ServiceMethod

Send to a specific method on a named service (D19, K2.1).

The router resolves the service via ServiceRegistry and wraps the payload with method metadata for the receiving agent.

Fields

service: String

Service name to resolve.

method: String

Method to invoke on the service.

Kernel

Send to the kernel itself.

RemoteNode

Route to a specific process on a remote node (K6). The inner target is resolved on the destination node.

Fields

node_id: String

Remote node identifier.

target: Box<MessageTarget>

Target to resolve on the remote node.
