Enum ScheduleError 

#[non_exhaustive]
pub enum ScheduleError {
    TooFewDates {
        stated: usize,
    },
    OutOfOrder {
        at: usize,
        date: NaiveDate,
        next: NaiveDate,
    },
    RepeatedDate {
        at: usize,
        date: NaiveDate,
    },
    StubDateOutsideTerm {
        date: NaiveDate,
        effective: NaiveDate,
        termination: NaiveDate,
    },

        last_regular_end: NaiveDate,
    },

Why a stated list of boundary dates is not a schedule.

Each variant is a way the list is ill-formed, never a way it is unconventional: a boundary on a Saturday and periods of unequal length are what stating dates is for, and neither is refused.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooFewDates

Fewer than two dates were stated. n boundaries delimit n - 1 periods, so one date delimits none and is not a schedule.

Fields

stated: usize

How many dates were stated.

OutOfOrder

Two consecutive dates run backwards.

Fields

at: usize

The zero-based index of the earlier of the offending pair.

date: NaiveDate

The date at at.

next: NaiveDate

The date at at + 1, which does not follow it.

RepeatedDate

The same date was stated twice in a row, which would delimit a period of zero length.

Fields

at: usize

The zero-based index of the first of the two.

date: NaiveDate

The repeated date.

StubDateOutsideTerm

A stated regular-period date — first regular start or last regular end — does not fall strictly inside the term.

Fields

date: NaiveDate

The stated date.

effective: NaiveDate

The schedule’s effective date.

termination: NaiveDate

The schedule’s termination date.

StubDatesOutOfOrder

The first regular period start is not before the last regular period end, so no regular period lies between them.

Fields

first_regular_start: NaiveDate

The stated first regular period start.

last_regular_end: NaiveDate

The stated last regular period end.

Trait Implementations

impl Clone for ScheduleError

fn clone(&self) -> ScheduleError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ScheduleError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ScheduleError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ScheduleError

impl Error for ScheduleError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for ScheduleError

fn eq(&self, other: &ScheduleError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
