pub async fn fetch_status(endpoint: &ControlEndpoint) -> Result<ProcStatus>Expand description
Ask a process for its status document once.
Errors mean unreachable or unparseable, which is not the same as
unhealthy: a process that has not yet bound its socket is indistinguishable
here from one that never will. Callers deciding readiness should poll with
wait_ready rather than treating one error as a verdict.
