Struct OccurrenceExceptions 

pub struct OccurrenceExceptions { /* private fields */ }

Which occurrences of which series are not there, for one run.

Built from the whole task list because a replacement lives in an entry of its own — possibly in another file of the same scan. An exception therefore reaches only as far as the scan does, which ADR-0031 states as a consequence.

Implementations

impl OccurrenceExceptions

pub fn from_tasks(tasks: &[Task]) -> Self

Collect every (SERIES_ID, RECURRENCE_ID) pair in the run.

pub fn dates_for(&self, task: &Task) -> ExcludedOccurrences

Every occurrence task does not have: what it cancelled itself, and what other entries of the run replace.

The one place that answers the question, and it answers it once per task: the day-by-day walk of a week or a month reads a set instead of re-reading properties on every cell.
