Module classification 

What may be done about a ledger error code: the one place retryability is decided. How long to wait is super::backoff; which Suotar codes map to which error code is the worker’s Suotar adapter’s.

Enums

Retryability

What may be done about an error code. The class is the contract’s, not the endpoint’s: the import phase is the only place that upgrades a code to Retryability::VerifyOnly.

Functions

is_enrolment_error

The answers that would send the student off to enrol.

is_repeatable_rejection

Whether Sisu answers an unchanged resend of a row carrying code the same way: the rejection is about what we sent or whom we sent it for, not about the moment it was sent.

is_waiting_error

Whether a row carrying code only awaits something outside the pipeline, so its answer is no failure: a submission Suotar cannot find yet, or an enrolment the student has not made.
