Enum ArithmeticError 

pub enum ArithmeticError {
    Unit {
        value: &'static str,
        unit: &'static str,
    },
    Range,
    Calendar {
        source: Error,
    },
}

Why a date or time could not be moved by a quantity.

Variants

Unit

The unit does not apply to the value, as an hour does not to a date (N1 §6.7.1).

Fields

value: &'static str

The kind of value.

unit: &'static str

The unit’s keyword.

Range

The result leaves the range 0001 to 9999 (N1 §6.7).

Calendar

The calendar arithmetic itself failed, as for a span past its limits.

Fields

source: Error

The calendar library’s failure.

Trait Implementations

impl Clone for ArithmeticError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArithmeticError

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

Formats the value using the given formatter.

impl Display for ArithmeticError

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

Formats the value using the given formatter.

impl Error for ArithmeticError

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.
