Enum DurationFormatterOptionsError 

#[non_exhaustive]
pub enum DurationFormatterOptionsError {
    DisplayAlwaysFractional,
    PreviousFractional,
    PreviousNumeric,
    FractionalDigitsOutOfRange,
}

Error type for DurationFormatterOptions validation.

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.

DisplayAlwaysFractional

A unit field is set to FieldDisplay::Always and the style is set to Fractional.

PreviousFractional

A previous unit’s style is Fractional, but the following unit’s style is not Fractional.

PreviousNumeric

A previous unit’s style is set to Numeric or TwoDigit and the following unit’s style is not Fractional, Numeric, or TwoDigit.

FractionalDigitsOutOfRange

The number of fractional digits is out of acceptable range. See FractionalDigits::Fixed.
