Enum DaemonControl 

#[non_exhaustive]
pub enum DaemonControl {
    Shutdown {
        grace_period_ms: u64,
    },
    DrainStart {
        grace_period_ms: u64,

Supervisor → daemon control event. Delivered via MeshDaemon::on_control. Carries relative-duration deadlines (no Instant) so a daemon running under any clock source can react.

The MeshOS-side richer form MeshOsControl carries Instant deadlines for SDK scheduling; the supervisor integration layer converts via MeshOsControl::to_daemon_control(now).

#[non_exhaustive] so later phases add control variants without breaking daemon implementations.

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.

Shutdown

Graceful shutdown. The daemon should finish in-flight work and exit before grace_period_ms elapses. Past the deadline the supervisor force-terminates.

Fields

grace_period_ms: u64

Milliseconds the daemon has before the supervisor force-terminates.

DrainStart

Drain start. Stop accepting new work; in-flight work continues until grace_period_ms elapses or DrainFinish arrives.

Fields

grace_period_ms: u64

Milliseconds the drain has before forced cutoff.

DrainFinish

Drain done. The daemon should exit immediately; in-flight work may be abandoned.

BackpressureOn

Cluster-wide backpressure is asserted. The daemon should reduce optional work (cache warmup, background indexing, etc.) proportional to level ∈ [0.0, 1.0]. 1.0 means “pause optional work entirely”.

Fields

level: f32

Severity in [0.0, 1.0]. 0 means just-barely triggered, 1 means catastrophic queue depth.

BackpressureOff

Cluster-wide backpressure cleared. Resume normal work.

Trait Implementations

impl Clone for DaemonControl

fn clone(&self) -> DaemonControl

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DaemonControl

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for DaemonControl

fn eq(&self, other: &DaemonControl) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
