pub async fn get_manual_linking_email_sends(
conn: &mut PgConnection,
course_ids: &[Uuid],
) -> ModelResult<Vec<ManualLinkingEmailSend>>Expand description
The linking emails sent by hand on these courses, newest first.
An action without details.emailed_to, as the earliest ones are, is matched to the ledger row its
send claimed: the newest one for the same course and student number claimed at most a minute before
the action. The per person and course quiet period leaves no other row in that window.
