ProcState

cloud::proc_control

Enum ProcState 

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

Lifecycle vocabulary of a supervised process.

Deliberately identical to kamaji_proto::WorkloadState so a workload’s own report can be handed to the supervisor without a translation table that would rot the first time either side gained a state. Kept as a separate type rather than a re-export only because this crate must not force a kamaji-proto dependency on every consumer of the status document.

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§

Source§

impl ProcState

Source

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”.

Source

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.
