Enum ShepherdMessage 

pub enum ShepherdMessage {
    Shutdown,
    Action {
        name: String,
        params: Option<String>,
        id: u64,
    },
}

Daemon -> child message

Variants

Shutdown

Graceful-stop request (shutdown_with_message)

Action

Custom action dispatch

Fields

name: String

The action name

params: Option<String>

Argument text for the action, passed through to the child verbatim; None when triggered without any.

Omitted from the wire when None, so a message with no arguments round-trips byte-identical.

One opaque string, not structured data: the daemon never reads it, so an app parses it in whatever grammar it already has.

id: u64

This dispatch’s correlation id, unique for the life of the daemon. Echo it back on your ChildMessage::ActionReply as id and the daemon matches your answer to this exact request rather than to its name.

Always present, unlike params. Treat it as an opaque token to hand back: u64 and increasing are implementation details, not a promise.
