Enum Warning 

#[non_exhaustive]
pub enum Warning {
    W0001,
    W0002,
    W0003,
    W0004,
    W0005,
    W0006,
}

A diagnostic warning from Appendix E’s W-series.

Warnings are separate from Code because they never abort an operation: they accompany a value that was produced, and the caller decides what to do. Rule R requires lossy renderings to be reported, and §8.4 requires a stale leap-second table to warn with a bounded error rather than convert silently.

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.

W0001

Precision loss in the requested rendering (Rule R).

W0002

Leap-second table may be stale; the bounded error is reported with it.

W0003

Body parameter evaluated outside its validity window (Rule C).

W0004

Cosmology enclosure width exceeds one tick.

W0005

Value produced by a legacy, non-derived calendar (§8.6).

W0006

Quantity comparable to or smaller than BIG_BANG_CLAIM; the datum’s physical identification is uncertain at this scale (§10.6).

Implementations

impl Warning

pub const fn as_str(self) -> &'static str

The wire-stable code string, e.g. "UCAL-W0001".

pub const fn describe(self) -> &'static str

One-line description, matching Appendix E.

Trait Implementations

impl Clone for Warning

fn clone(&self) -> Warning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Warning

impl Debug for Warning

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

Formats the value using the given formatter.

impl Display for Warning

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

Formats the value using the given formatter.

impl Eq for Warning

impl Hash for Warning

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Warning

fn cmp(&self, other: &Warning) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

impl PartialEq for Warning

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Warning

fn partial_cmp(&self, other: &Warning) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
