Expand description

A list of error outcomes for various operations in the icu_calendar crate.

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`

Fields

field: &'static str

The name of the field

max: usize

The maximum value

An input overflowed its range.

`Underflow`

Fields

field: &'static str

The name of the field

min: isize

The minimum value

An input underflowed its range.

`OutOfRange`

Out of range

`UnknownEra(TinyAsciiStr<16_usize>, &'static str)`

Unknown era

`UnknownMonthCode(TinyAsciiStr<4_usize>, &'static str)`

Unknown month code for a given calendar

`MissingInput(&'static str)`

Missing required input field for formatting

`UnknownAnyCalendarKind(TinyAsciiStr<16_usize>)`

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

impl CalendarError

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

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");
