Enum Unenumerable 

pub enum Unenumerable {
    Interval,
    UnboundedSetElement,
    YearRangeOverflow,
}

Why Edtf::values cannot enumerate an expression (decisions D24–D25).

Variants

Interval

Intervals denote a single continuous extent, not a collection of values (ISO 8601-2 Clause 10 defines no enumeration for them).

UnboundedSetElement

The set contains a ..date or date.. element, whose value set is unbounded (§6.3 a–b give “indication”, not “expansion”).

YearRangeOverflow

A significant-digit sweep or range endpoint lies beyond the years this library computes with — the same cases where bounds() reports Bound::Unknown.

Trait Implementations

impl Clone for Unenumerable

fn clone(&self) -> Unenumerable

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Unenumerable

impl Debug for Unenumerable

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

Formats the value using the given formatter.

impl Display for Unenumerable

impl Eq for Unenumerable

impl Error for Unenumerable

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 Unenumerable

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

Equality operator ==.

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

Inequality operator !=.
