Struct WindowsParserBorrowed

pub struct WindowsParserBorrowed<'a> { /* private fields */ }

A borrowed wrapper around the windows time zone mapper data.

Implementations

impl WindowsParserBorrowed<'static>

pub fn static_to_owned(&self) -> WindowsParser

Cheaply converts a [WindowsParserBorrowed<'static>] into a WindowsParser.

Note: Due to branching and indirection, using WindowsParser might inhibit some compile-time optimizations that are possible with WindowsParserBorrowed.

impl WindowsParserBorrowed<'_>

pub fn new() -> Self

Creates a new static WindowsParserBorrowed.

pub fn parse(self, windows_tz: &str, region: Option<Region>) -> Option<TimeZone>

Returns the BCP-47 ID for a provided Windows time zone and [Region] with a case sensitive query.

If no region is provided or the specificity is not required, then the territory will default to the M.49 World Code, 001.

use icu::locale::subtags::region;
use icu::time::{zone::WindowsParser, TimeZone};
use tinystr::tinystr;

let win_tz_mapper = WindowsParser::new();

let bcp47_id = win_tz_mapper.parse("Central Standard Time", None);
assert_eq!(bcp47_id, Some(TimeZone(tinystr!(8, "uschi"))));

let bcp47_id =
    win_tz_mapper.parse("Central Standard Time", Some(region!("US")));
assert_eq!(bcp47_id, Some(TimeZone(tinystr!(8, "uschi"))));

let bcp47_id =
    win_tz_mapper.parse("Central Standard Time", Some(region!("CA")));
assert_eq!(bcp47_id, Some(TimeZone(tinystr!(8, "cawnp"))));

pub fn parse_from_utf8( self, windows_tz: &[u8], region: Option<Region>, ) -> Option<TimeZone>

See Self::parse.
