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 the daemon never reads, so an app parses it in its own grammar.

id: u64

This dispatch’s correlation id, unique for the life of the daemon. Echo it back as id on your ChildMessage::ActionReply. The daemon then matches your answer to this request, not to its name.

Always present, unlike params. Treat u64 and increasing as implementation details, not a promise.
