Enum BusEvent 

#[non_exhaustive]
pub enum BusEvent {
    Process {
        event: ProcessEventKind,
        info: ProcessInfo,
        manually: bool,
        at_ms: u64,
    },
    LogOut {
        id: u32,
        line: String,
    },
    LogErr {
        id: u32,
        line: String,
    },
    Channel {
        id: u32,

    Dropped {
        count: u64,
    },
    DaemonShutdown,
}

One event on the daemon bus

Uses adjacently tagged serde format with event discriminator and data wrapper. Subscription TOPICS are the dotted strings from BusEvent::topic (process.exit, log.out, daemon.* — spec §6 grammar). Phase 2’s server-side filter globs against topic().

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

Lifecycle event for one sheep

Fields

event: ProcessEventKind

What happened

info: ProcessInfo

Sheep snapshot at event time

manually: bool

True when a user action caused it

at_ms: u64

Unix millis

LogOut

One stdout line from a sheep

Fields

id: u32

Sheep id

line: String

The line (no trailing newline)

LogErr

One stderr line from a sheep

Fields

id: u32

Sheep id

line: String

The line

Channel

One message a sheep wrote on its shepherd channel (fd 3).

Child->shepherd only. The shepherd’s own writes — the {"kind":"shutdown"} of shutdown_with_message, and an action a Trigger dispatched — are deliberately not here. Every one of them is something an operator or the daemon just did and already has a reporter: a shutdown message is followed by process.stop, and an action is answered to the caller that sent it by Response::Triggered. Putting them here as well would make this the only event on the bus reporting a REQUEST rather than an outcome, and would loop a dog that both subscribes and triggers back onto its own dispatches. Adding the outbound half later stays additive — another variant, more channel. topics, no version bump — so this is a narrowing, not a door closed.

message is the app’s own text, whole and unredacted, unlike the [dog.<name>] config that travels as DogSectionToml. Nothing on this wire is a credential: Ready is empty, Metric is a name and a float, and an ActionReply body is text the app chose to publish to whoever triggered it. That is what makes a derived Debug safe here.

Fields

id: u32

The sheep that wrote it.

message: ChildMessage

The message, exactly as it came off fd 3.

Dropped

The bounded queue dropped this many events for this subscriber

Fields

count: u64

Dropped-event count since last notice

DaemonShutdown

Daemon is shutting down
