Enum ProcState 

pub enum ProcState {
    Pending,
    Starting,
    Running,
    Draining,
    Exited,
    Failed,
}

Lifecycle vocabulary of a supervised process.

Deliberately identical to [kamaji_proto::WorkloadState] on the wire. Kept as a separate type rather than a re-export so the default build of this crate — the one a workload links — carries no supervisor protocol at all.

Variants

Pending

Accepted, nothing started yet.

Starting

Started, not yet serving — booting, migrating, warming a cache.

Running

Serving. This is the only state that counts as ready.

Draining

Shutting down gracefully.

Exited

Exited cleanly.

Failed

Exited with a failure, or reported itself unrecoverable.

Implementations

impl ProcState

pub fn is_ready(self) -> bool

Whether a process in this state is ready to be used.

Starting is deliberately not ready: the entire point of the channel is to distinguish “the port is open” from “I am serving”.

pub fn is_terminal(self) -> bool

Whether this state is terminal — no amount of further polling changes it, so a readiness wait should fail fast rather than burn its timeout.

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

The wire token, which is also what an operator reads in a log line.
