Enum ErrorKind 

pub enum ErrorKind {
    Other,
    TimedOut,
    CallFailed,
    UncertainWrite,
}

Why a call failed, where the answer changes what to do about it.

Variants

Other

TimedOut

The call ran past its deadline and was killed. Worth its own kind because asking again means waiting exactly as long again, which is the one failure where a retry costs more than it can possibly win.

CallFailed

The CLI itself could not answer: a non-zero exit, or an error event in place of a message. Distinct from an answer that arrived and could not be parsed, which is what the retry exists for and which a model corrects readily when told what was wrong. Nothing about a refusal, a quota, or a crash is corrected by being asked the same thing again.

UncertainWrite

A write failed locally, but the destination could not be reread to tell whether it landed. Repeating it blindly could duplicate the write.
