Enum icu::timezone::ParseError

pub enum ParseError {
    Syntax(ParseError),

The error type for parsing IXDTF syntax strings in icu_timezone.

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.

Syntax(ParseError)

Syntax error for IXDTF string.

Range(RangeError)

Parsed record is out of valid date range.

Date(DateError)

Parsed date and time records were not a valid ISO date.

MissingFields

There were missing fields required to parse component.

InconsistentTimeZoneOffsets

There were two offsets provided that were not consistent with each other.

InvalidOffsetError

There was an invalid Offset.

MismatchedTimeZoneFields

The set of time zone fields was not expected for the given type. For example, if a named time zone was present with offset-only parsing, or an offset was present with named-time-zone-only parsing.

UnknownCalendar

An unknown calendar was provided.

RequiresCalculation

A timezone calculation is required to interpret this string, which is not supported.

Example

use icu::timezone::{IxdtfParser, ParseError};

// This timestamp is in UTC, and requires a time zone calculation in order to display a Zurich time.
assert_eq!(
    IxdtfParser::new().try_loose_iso_from_str("2024-08-12T12:32:00Z[Europe/Zurich]").unwrap_err(),
    ParseError::RequiresCalculation,
);

// These timestamps are in local time
IxdtfParser::new().try_loose_iso_from_str("2024-08-12T14:32:00+02:00[Europe/Zurich]").unwrap();
IxdtfParser::new().try_loose_iso_from_str("2024-08-12T14:32:00[Europe/Zurich]").unwrap();

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl From<DateError> for ParseError

fn from(value: DateError) -> ParseError

Converts to this type from the input type.

impl From<InvalidOffsetError> for ParseError

fn from(_: InvalidOffsetError) -> ParseError

Converts to this type from the input type.

impl From<ParseError> for ParseError

fn from(value: ParseError) -> ParseError

Converts to this type from the input type.

impl From<RangeError> for ParseError

fn from(value: RangeError) -> ParseError

Converts to this type from the input type.

impl PartialEq for ParseError

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