pub fn any_attained_by_person<'a>(
existing: &'a [ExistingAttainment],
sisu_person_id: &str,
) -> Option<&'a ExistingAttainment>Expand description
Any attainment the registry holds, for when no enrolment names the course unit. The response is scoped to one student and one course code already; the person is checked because nothing else here is.
