pub struct IanaParserBorrowed<'a> { /* private fields */ }
Expand description
A borrowed wrapper around the time zone ID parser, returned by
IanaParser::as_borrowed()
. More efficient to query.
Implementations§
Source§impl IanaParserBorrowed<'static>
impl IanaParserBorrowed<'static>
Sourcepub fn new() -> IanaParserBorrowed<'static>
pub fn new() -> IanaParserBorrowed<'static>
Creates a new IanaParserBorrowed
using compiled data.
See IanaParserBorrowed
for an example.
✨ Enabled with the compiled_data
Cargo feature.
Sourcepub fn static_to_owned(&self) -> IanaParser
pub fn static_to_owned(&self) -> IanaParser
Cheaply converts a [IanaParserBorrowed<'static>
] into a IanaParser
.
Note: Due to branching and indirection, using IanaParser
might inhibit some
compile-time optimizations that are possible with IanaParserBorrowed
.
Source§impl<'a> IanaParserBorrowed<'a>
impl<'a> IanaParserBorrowed<'a>
Sourcepub fn parse(&self, iana_id: &str) -> TimeZone
pub fn parse(&self, iana_id: &str) -> TimeZone
Gets the BCP-47 time zone ID from an IANA time zone ID with a case-insensitive lookup.
Returns TimeZone::unknown()
if the IANA ID is not found.
§Examples
use icu_time::zone::iana::IanaParser;
use icu_time::TimeZone;
let parser = IanaParser::new();
let result = parser.parse("Asia/CALCUTTA");
assert_eq!(*result, "inccu");
// Unknown IANA time zone ID:
assert_eq!(parser.parse("America/San_Francisco"), TimeZone::unknown());
Sourcepub fn parse_from_utf8(&self, iana_id: &[u8]) -> TimeZone
pub fn parse_from_utf8(&self, iana_id: &[u8]) -> TimeZone
Same as Self::parse()
but works with potentially ill-formed UTF-8.
Sourcepub fn iter(&self) -> TimeZoneIter<'a> ⓘ
pub fn iter(&self) -> TimeZoneIter<'a> ⓘ
Returns an iterator over all known time zones.
§Examples
use icu::time::zone::IanaParser;
use icu::time::zone::TimeZone;
use std::collections::BTreeSet;
use tinystr::tinystr;
let parser = IanaParser::new();
let ids = parser.iter().collect::<BTreeSet<_>>();
assert!(ids.contains(&TimeZone(tinystr!(8, "uaiev"))));
