Enum PeriodError 

#[non_exhaustive]
pub enum PeriodError {
    IncompatibleUnits {
        left: Period,
        right: Period,
    },
    Unordered {
        left: Period,
        right: Period,
    },
}

Error combining or ordering two Periods.

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.

IncompatibleUnits

The operands belong to different unit families (e.g. Month and Day), or one is Term, so the result has no well-defined unit.

Fields

left: Period

The left-hand operand.

right: Period

The right-hand operand.

Unordered

The two tenors have no order: their day spans overlap without being equal (1M against 30D), or one is Term.

Fields

left: Period

The left-hand operand.

right: Period

The right-hand operand.

Trait Implementations

impl Clone for PeriodError

fn clone(&self) -> PeriodError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PeriodError

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

Formats the value using the given formatter.

impl Display for PeriodError

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

Formats the value using the given formatter.

impl Eq for PeriodError

impl Error for PeriodError

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 PeriodError

fn eq(&self, other: &PeriodError) -> 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.
