Function request_level_outcome 

pub fn request_level_outcome(
    operation: RegistryOperation,
    kind: RegistryErrorKind,
    facts: &RowFacts,
) -> Outcome

The outcome for every row of a batch Suotar rejected as a whole. On import all that matters is whether the request could have been acted on: a connection that never opened proves it was not. A waiting row’s lookup keeps waiting only through an outage; a refusal of the request itself would come back every retry, so it ages out like any other failure.
