Struct CompetingCredits 

Source 
pub(super) struct CompetingCredits {
    registered_by_us: Vec<LiveSuccessForModule>,
    recorded_locally: Vec<RecordedCredit>,
}
Expand description

The credits outside Sisu this attempt’s grade competes with for the module: what we registered from the student’s other attempts, which Suotar’s copy of Sisu may predate, and the credits our records hold.

Fields§

§registered_by_us: Vec<LiveSuccessForModule>§recorded_locally: Vec<RecordedCredit>

Implementations§

Source§

impl CompetingCredits

Source

pub(super) async fn load( tx: &mut PgConnection, lookup: &AnsweredLookup<'_>, ) -> CreditRegistrationResult<Self>

Locks our registered successes only for a listed answer, the one that can freeze a payload superseding them, and reads the recorded credits only for an enrolment error, the one answer they can overrule. Call inside the transaction that writes the resolution.

Source

fn supersedes(&self) -> Vec<Uuid>

The registrations a frozen payload replaces once it is registered.
