Enum MeshOsControl 

#[non_exhaustive]
pub enum MeshOsControl {
    Shutdown {
        deadline: Instant,
    },
    DrainStart {
        deadline: Instant,
    },
    DrainFinish,
    BackpressureOn {
        level: f32,
    },
    BackpressureOff,
}

Supervisor → daemon control event. Delivered via the per-daemon control channel (separate from the process() event stream). The daemon implements on_control(&mut self, event: MeshOsControl) (default impl ignores everything).

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

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 deadline. Past the deadline the supervisor force-terminates.

Fields

deadline: Instant

Wall-clock deadline by which the daemon should be gone. Past this, the supervisor force-terminates.

DrainStart

Drain start. Stop accepting new work; in-flight work continues until MeshOsControl::DrainFinish arrives or the deadline elapses.

Fields

deadline: Instant

Deadline by which drain should be complete.

DrainFinish

Drain done. All in-flight work that’s still running may be abandoned; the daemon should exit.

BackpressureOn

Cluster-wide backpressure is active. The daemon should reduce optional work (cache warmup, background indexing, etc.) by roughly 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.

Implementations

impl MeshOsControl

pub fn to_daemon_control(&self, now: Instant) -> DaemonControl

Convert this SDK-internal event to the WASM-friendly DaemonControl form the daemon’s on_control method receives. now anchors the relative-ms conversion of the Instant deadlines; deadlines in the past clamp to 0.

Trait Implementations

impl Clone for MeshOsControl

fn clone(&self) -> MeshOsControl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MeshOsControl

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

Formats the value using the given formatter.

impl PartialEq for MeshOsControl

fn eq(&self, other: &MeshOsControl) -> 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.
