Lifecycle event a DaemonLifecycleObserver receives when a daemon’s state on this node changes. Plain-data (no references) so observers can buffer / async-forward without lifetime issues.

The integration with MeshOS lives in behavior::meshos::sources — a MeshOsDaemonLifecycleSink impls this trait and translates each event to the matching MeshOsEvent::DaemonLifecycle.

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.

Registered

Daemon registered on this node.

Fields

id: u64

MeshDaemon::origin_hash.

name: String

MeshDaemon::name.

at: Instant

Monotonic timestamp of the registration.

Unregistered

Daemon unregistered (either via cleanup or migration source-side teardown).

Fields

id: u64

MeshDaemon::origin_hash.

name: String

Last known name (carried so observers don’t need to look it up post-unregister).

at: Instant

Monotonic timestamp of the unregistration.

Crashed

Daemon crashed during process().

Fields

id: u64

MeshDaemon::origin_hash.

name: String

MeshDaemon::name.

at: Instant

Monotonic timestamp of the crash.

reason: String

Operator-readable reason from the daemon-side error.

HealthChanged

Daemon’s self-reported health changed (poller observed a transition from the previous sample).

Fields

id: u64

MeshDaemon::origin_hash.

name: String

MeshDaemon::name.

at: Instant

Monotonic timestamp of the observation.

health: DaemonHealth

New health value.

SaturationChanged

Daemon’s self-reported saturation changed (poller observed a transition exceeding the configured noise floor — see behavior::meshos for the threshold).

Fields

id: u64

MeshDaemon::origin_hash.

name: String

MeshDaemon::name.

at: Instant

Monotonic timestamp of the observation.

saturation: f32

New saturation value, [0.0, 1.0].
