Expand description

A list of error outcomes for various operations in this module.

Re-exported as Error.

Variants (Non-exhaustive)§

This enum is marked as 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.
§

Parse

An input could not be parsed.

§

Overflow

An input overflowed its range.

Fields

§field: &'static str

The name of the field

§max: usize

The maximum value

§

Underflow

An input underflowed its range.

Fields

§field: &'static str

The name of the field

§min: isize

The minimum value

§

OutOfRange

Out of range

§

UnknownEra(TinyStr16, &'static str)

Unknown era

§

UnknownMonthCode(TinyStr4, &'static str)

Unknown month code for a given calendar

§

MissingInput(&'static str)

Missing required input field for formatting

§

UnknownAnyCalendarKind(TinyStr16)

No support for a given calendar in AnyCalendar

§

MissingCalendar

An operation required a calendar but a calendar was not provided.

§

Data(DataError)

An error originating inside of the data provider.

Implementations§

source§

impl CalendarError

source

pub fn unknown_any_calendar_kind(description: impl Writeable) -> Self

Create an error when an AnyCalendarKind is expected but not available.

§Examples
use icu::calendar::AnyCalendarKind;
use icu::calendar::CalendarError;

let cal_str = "maori";

AnyCalendarKind::get_for_bcp47_string(cal_str)
    .ok_or_else(|| CalendarError::unknown_any_calendar_kind(cal_str))
    .expect_err("Māori calendar is not yet supported");
