Enum GuardFailure 

pub enum GuardFailure {
    Start(String),
    Panicked(String),
    Quiet(Duration),
    Ceiling(Duration),
    Vanished,
}

What: Why a guarded job produced no result. Why: Each cause names a different way forward for the person.

In TS you’d write (pseudocode):

type GuardFailure = { kind: 'start'; reason } | { kind: 'panicked'; reason } | { kind: 'quiet'; windowMs } | { kind: 'ceiling'; ceilingMs } | { kind: 'vanished' };

Variants

Start(String)

The operating system would not start the thread.

Panicked(String)

The job panicked; the text is the panic’s message.

Quiet(Duration)

The job showed no sign of work for the window and was abandoned.

Ceiling(Duration)

The job ran as long as the ceiling allows, whatever it showed, and was abandoned.

Vanished

The thread ended without sending a result or a panic, which no code path here does.
