A borrowed wrapper around the windows time zone mapper data.

Implementations

impl WindowsTimeZoneMapperBorrowed<'_>

pub fn new() -> Self

Creates a new static WindowsTimeZoneMapperBorrowed.

pub fn windows_tz_to_bcp47_id( &self, windows_tz: &str, region: Option<Region>, ) -> Option<TimeZoneBcp47Id>

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::timezone::{TimeZoneBcp47Id, WindowsTimeZoneMapper};
use tinystr::tinystr;

let win_tz_mapper = WindowsTimeZoneMapper::new();

let bcp47_id =
    win_tz_mapper.windows_tz_to_bcp47_id("Central Standard Time", None);
assert_eq!(bcp47_id, Some(TimeZoneBcp47Id(tinystr!(8, "uschi"))));

let bcp47_id = win_tz_mapper
    .windows_tz_to_bcp47_id("Central Standard Time", Some(region!("US")));
assert_eq!(bcp47_id, Some(TimeZoneBcp47Id(tinystr!(8, "uschi"))));

let bcp47_id = win_tz_mapper
    .windows_tz_to_bcp47_id("Central Standard Time", Some(region!("CA")));
assert_eq!(bcp47_id, Some(TimeZoneBcp47Id(tinystr!(8, "cawnp"))));
