Struct icu::locale::extensions::unicode::SubdivisionSuffix

source ·
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§

source§

impl SubdivisionSuffix

source

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());
source

pub const fn try_from_utf8( code_units: &[u8], ) -> Result<SubdivisionSuffix, ParseError>

source

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.

source

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.

source

pub const fn into_raw(self) -> [u8; 4]

Deconstructs into a raw format to be consumed by from_raw_unchecked or try_from_raw.

source

pub const fn as_str(&self) -> &str

A helper function for displaying as a &str.

source

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().

source

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.

impl SubdivisionSuffix

source

pub fn to_string(&self) -> String

Converts the given value to a String.

Under the hood, this uses an efficient [Writeable] implementation. However, in order to avoid allocating a string, it is more efficient to use [Writeable] directly.
