Errors

• NormalizeError::MissingName — name is empty.
• NormalizeError::InvalidName — name contains a path separator or is ./...
• NormalizeError::MissingScript — script is empty.
• NormalizeError::ZeroInstances — instances == 0.
• NormalizeError::InvalidCron — cron_restart is not valid in croner’s dialect (carries the pattern and the rejection reason).
• NormalizeError::InvalidTimezone — cron_timezone is not a name in the IANA time-zone database.
• NormalizeError::InvalidProbe — readiness_probe or liveness_probe has a target ProbeTarget::parse rejects (carries which probe and the rendered reason).
• NormalizeError::ZeroFailureThreshold — a probe’s failure_threshold is explicitly 0.
• NormalizeError::IntervalBelowMinimum — a probe’s interval is under the floor its own loop honours: a full second for liveness_probe, and only “greater than zero” for readiness_probe (carries which probe, the value and the floor).
• NormalizeError::ZeroMaxMemory — max_memory is 0.
• NormalizeError::ActionTimeoutTooLong — action_timeout is at or above the ceiling no RPC caller could ever be given room to wait past (carries the app name, the value and the ceiling).
• NormalizeError::InvalidKillSignal — kill_signal names a signal the daemon’s stop ladder cannot send (carries the app name and the value).
• NormalizeError::WatchWithoutCwd — watch is true with no cwd set.
• NormalizeError::ZeroWatchDelay — watch_delay is 0.
• NormalizeError::InvalidWatchGlob — a watch_options or ignore_watch pattern globset will not compile (carries the app name, which of the two lists, the pattern and the reason).
