Enum SignalOutcome 

pub enum SignalOutcome {
    Sent,
    AlreadyGone,
    Refused(String),
}

What sending one signal to a record’s process did.

Variants

Sent

The signal was delivered to the process that wrote the record.

AlreadyGone

Nothing was signalled: the process that wrote the record is no longer there.

Refused(String)

Something holds the pid and no signal reached it: the kernel refused kill(2), and the string is the errno description, EPERM included; or the pid is ProcessState::Unverified, kill(2) was never called, and the string is that reason.
