Enum SignalOutcome 

#[non_exhaustive]
pub enum SignalOutcome {
    Delivered,
    NotRunning,
    Failed {
        reason: String,
    },
}

What happened when the shepherd tried to deliver one signal.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Delivered

The kernel accepted the signal for this sheep’s pid.

Says the signal was delivered, not that the app did anything with it. A signal the app blocks or ignores is Delivered too.

NotRunning

The sheep is registered but has no live process to signal: stopped, errored, or waiting out a restart backoff.

Failed

The kernel refused the delivery; carries its reason (ESRCH for a process reaped between the lookup and the syscall, EPERM for one this daemon may not signal).

Fields

reason: String

The refusal, as the OS worded it.
