Enum FlowHalt 

pub enum FlowHalt {
    FirstStage,
    LaterStage,
}

Which stage a halted flow walk stopped on. The distinction the outcome turns on is only ever first-versus-later: the first stage is the run’s own attempt at the work and its failure is fully described by the process exit already in evidence, while a later one halting means earlier stages passed and whatever they produced is worth preserving.

Variants

FirstStage

The flow’s first stage failed.

LaterStage

A stage after the first failed, or the driver could not carry the walk past one.
