Enum TelemetryUnavailabilityReason 

pub enum TelemetryUnavailabilityReason {
    WorkerLacksTelemetry,
    ParseFailed,
    Pruned,
    DaemonRestarted,
    PollerOverloaded,
    NeverArrived,
}

Why a worker’s telemetry age is unknown / unusable. Ordered by diagnostic precedence (most fundamental cause first).

Variants

WorkerLacksTelemetry

The worker binary does not provide rch-wkr telemetry.

ParseFailed

The most recent telemetry payload failed to parse.

Pruned

The last retained sample was pruned by retention before re-sampling.

DaemonRestarted

The daemon restarted and lost in-memory samples; none re-collected yet.

PollerOverloaded

The observer/poll loop is saturated or behind, so no fresh sample exists.

NeverArrived

Telemetry simply has not arrived yet (first sample pending).

Implementations

impl TelemetryUnavailabilityReason

pub const fn as_str(self) -> &'static str

Stable snake_case identifier (matches the serialized form).

pub const fn explanation(self) -> &'static str

Operator-facing explanation.

pub const fn is_observer_side(self) -> bool

Whether the cause is the observer (daemon/poller) rather than the worker. Observer-side causes must NOT be read as “the worker is broken”.
