Module enrolment_selection 

Which of a student’s enrolments the attainment is registered against. A study right that covers the attainment date first, since Sisu refuses one that does not; then degree before open university: a degree student who also holds an open-university study right wants the credit inside their degree.

Structs

EnrolmentCriteria

Enums

NoUsableEnrolment

Why no enrolment could carry the attainment; each variant reads differently to the student.

Constants

CREDITS_TOLERANCE 🔒

Slack for the f32-to-f64 widening. Real credit amounts are never finer than 0.1.

DEGREE_KIND

ENROLLED_STATE

FAILED_STATE

RECOVERY_REGISTRATION_WINDOW_DAYS 🔒

How long after the submission its attainment may be registered and still count as its own.

Functions

attained_candidates

The attainments a new one must improve on: every entry on the student and course code that is not failed, matching the scope Suotar’s own import checks against.

attainment_matching_submission

The attainment a submission we lost track of would have produced, matched on what we sent.

credits_fit 🔒

Whether an enrolment’s registry-declared credit range can carry the module’s credits.

is_valid_attainment 🔒

preferred_attainment

The attainment sisu_attainment_id records: the course unit one when there is one, else the latest.

select_enrolment

The enrolment to register an attainment against, or why none will do: an accepted one whose credit range carries criteria.credits, preferring one whose study right covers the attainment date, then a degree study right, then one whose activity period covers it, then the latest enrolment.

valid_range 🔒

(min, max). A missing bound or min > max is the registry’s own data at fault, and as unusable as no range.
