👎Deprecated since 1.5.0: use
TimeZoneIdMapper
insteadExpand description
A mapper from IANA time zone identifiers to BCP-47 time zone identifiers.
§Examples
use icu::timezone::IanaToBcp47Mapper;
let mapper = IanaToBcp47Mapper::new();
let mapper_borrowed = mapper.as_borrowed();
// The IANA zone "Australia/Melbourne" is the BCP-47 zone "aumel"
assert_eq!(
mapper_borrowed.get("Australia/Melbourne"),
Some("aumel".parse().unwrap())
);
// Lookup is ASCII-case insensitive
assert_eq!(
mapper_borrowed.get("australia/melbourne"),
Some("aumel".parse().unwrap())
);
// The IANA zone "Australia/Victoria" is an alias
assert_eq!(
mapper_borrowed.get("Australia/Victoria"),
Some("aumel".parse().unwrap())
);

impl IanaToBcp47Mapper
sourcepub const fn new() -> Self
pub const fn new() -> Self
Creates a new IanaToBcp47Mapper
using compiled data.
See IanaToBcp47Mapper
for an example.
✨ Enabled with the compiled_data
Cargo feature.
sourcepub fn try_new_with_any_provider(
provider: &(impl AnyProvider + ?Sized),
) -> Result<Self, TimeZoneError>
pub fn try_new_with_any_provider( provider: &(impl AnyProvider + ?Sized), ) -> Result<Self, TimeZoneError>
A version of Self::new
that uses custom data provided by an AnyProvider
.
sourcepub fn try_new_unstable<P>(provider: &P) -> Result<Self, TimeZoneError>
pub fn try_new_unstable<P>(provider: &P) -> Result<Self, TimeZoneError>
A version of Self::new
that uses custom data provided by a DataProvider
.
⚠️ The bounds on provider may change over time, including in SemVer minor releases.
sourcepub fn as_borrowed(&self) -> IanaToBcp47MapperBorrowed<'_>
pub fn as_borrowed(&self) -> IanaToBcp47MapperBorrowed<'_>
Returns a borrowed version of the mapper that can be queried.
This avoids a small potential cost of reading the data pointer.
