Struct ExcludedOccurrences 

pub struct ExcludedOccurrences { /* private fields */ }

The occurrences one entry does not have, kept apart by reason.

Both reasons take the occurrence out of the day it would have fallen on. They part ways over the arrears: a cancelled occurrence never was, so the debt is whichever earlier one still stands, while a replaced occurrence did take place — elsewhere — and its debt travels with the entry that replaced it (ADR-0031).

Implementations

impl ExcludedOccurrences

pub fn contains(&self, date: &NaiveDate) -> bool

Whether the series skips date, for either reason.

pub fn is_replaced(&self, date: &NaiveDate) -> bool

Whether another entry of the run stands in for the occurrence on date.

Asked where the two reasons differ, which is the arrears bucket. A date named by both is treated as replaced: the occurrence is somewhere, and an EXDATE beside a replacement is redundant rather than contradictory.

pub fn is_empty(&self) -> bool

Whether this entry misses no occurrence at all — the fast path for the overwhelmingly common case of an entry without an exception.

pub fn len(&self) -> usize

How many occurrences are missing, counting a date named by both reasons twice. An upper bound is all the walks over a series need, and an exact count would cost a pass over the smaller set.
