Enum WorkerStatus 

#[repr(u8)]
pub enum WorkerStatus {
    Pending = 0,
    Ready = 1,
    NotReady = 2,
    Failed = 3,
    Draining = 4,
}

Worker lifecycle status, modeled after Kubernetes pod conditions.

Separates “starting up” from “can serve traffic” from “broken” to prevent premature removal of workers that haven’t been locally verified.

Uses #[repr(u8)] with explicit discriminants so atomic storage (AtomicU8) and wire compatibility do not depend on enum ordering.

Variants

Pending = 0

Just registered, not yet proven healthy locally. Not routable. Health checker probes until first success.

Ready = 1

Locally verified and passing health checks. Routable.

NotReady = 2

Was Ready, now failing readiness checks. Not routable. NOT removed — may recover. Health checker continues probing.

Failed = 3

Sustained liveness failure. Will be removed if --remove-unhealthy-workers.

Draining = 4

Marked for removal (e.g. K8s pod has deletionTimestamp). Excluded from selection so no new traffic is routed, but kept in the registry so in-flight requests can complete before the worker is removed.

Implementations

impl WorkerStatus

pub fn try_from_u8(value: u8) -> Option<Self>

Try to convert a u8 discriminant to a WorkerStatus. Returns None for unrecognized values.

pub fn from_u8(value: u8) -> Self

Convert a u8 discriminant to a WorkerStatus, falling back to Pending for unrecognized values (with a debug assertion).

pub fn is_routable(self) -> bool

Returns true if the worker is routable (only Ready).
