Struct icu_locale::extensions::unicode::SubdivisionSuffix
pub struct SubdivisionSuffix(/* private fields */);
Expand description
A subdivision suffix used in SubdivisionId
.
This suffix represents a specific subdivision code under a given Region
.
For example the value of SubdivisionId
may be gbsct
, where the SubdivisionSuffix
is sct
for Scotland.
Such a value associated with a key rg
means that the locale should use Unit Preferences
(default calendar, currency, week data, time cycle, measurement system) for Scotland, even if the
LanguageIdentifier
is en-US
.
A subdivision suffix has to be a sequence of alphanumerical characters no shorter than one and no longer than four characters.
§Examples
use icu::locale::extensions::unicode::{subdivision_suffix, SubdivisionSuffix};
let ss: SubdivisionSuffix =
"sct".parse().expect("Failed to parse a SubdivisionSuffix.");
assert_eq!(ss, subdivision_suffix!("sct"));
Implementations§
§impl SubdivisionSuffix
impl SubdivisionSuffix
pub const fn try_from_str(s: &str) -> Result<SubdivisionSuffix, ParseError>
pub const fn try_from_str(s: &str) -> Result<SubdivisionSuffix, ParseError>
A constructor which takes a str slice, parses it and
produces a well-formed SubdivisionSuffix
.
§Examples
use icu_locale_core::extensions :: unicode ::SubdivisionSuffix;
assert!(SubdivisionSuffix::try_from_str("sct").is_ok());
assert!(SubdivisionSuffix::try_from_str("toolooong").is_err());
pub const fn try_from_utf8(
code_units: &[u8],
) -> Result<SubdivisionSuffix, ParseError>
pub const fn try_from_utf8( code_units: &[u8], ) -> Result<SubdivisionSuffix, ParseError>
pub const fn try_from_raw(raw: [u8; 4]) -> Result<SubdivisionSuffix, ParseError>
pub const fn try_from_raw(raw: [u8; 4]) -> Result<SubdivisionSuffix, ParseError>
Safely creates a SubdivisionSuffix
from its raw format
as returned by Self::into_raw
. Unlike Self::try_from_utf8
,
this constructor only takes normalized values.
pub const unsafe fn from_raw_unchecked(v: [u8; 4]) -> SubdivisionSuffix
pub const unsafe fn from_raw_unchecked(v: [u8; 4]) -> SubdivisionSuffix
Unsafely creates a SubdivisionSuffix
from its raw format
as returned by Self::into_raw
. Unlike Self::try_from_utf8
,
this constructor only takes normalized values.
§Safety
This function is safe iff Self::try_from_raw
returns an Ok
. This is the case
for inputs that are correctly normalized.
pub const fn into_raw(self) -> [u8; 4]
pub const fn into_raw(self) -> [u8; 4]
Deconstructs into a raw format to be consumed by
from_raw_unchecked
or
try_from_raw
.
pub fn strict_cmp(self, other: &[u8]) -> Ordering
pub fn strict_cmp(self, other: &[u8]) -> Ordering
Compare with BCP-47 bytes.
The return value is equivalent to what would happen if you first converted
self
to a BCP-47 string and then performed a byte comparison.
This function is case-sensitive and results in a total order, so it is appropriate for
binary search. The only argument producing Ordering::Equal
is self.as_str().as_bytes()
.
pub fn normalizing_eq(self, other: &str) -> bool
pub fn normalizing_eq(self, other: &str) -> bool
Compare with a potentially unnormalized BCP-47 string.
The return value is equivalent to what would happen if you first parsed the BCP-47 string and then performed a structural comparison.
