Struct icu_locale::extensions::unicode::SubdivisionId

#[non_exhaustive]
pub struct SubdivisionId { pub region: Region, pub suffix: SubdivisionSuffix, }
Expand description

A Subivision Id as defined in Unicode Locale Identifier.

Subdivision Id is used in Unicode extensions:

  • rg - Regional Override
  • sd - Regional Subdivision

In both cases the subdivision is composed of a Region and a SubdivisionSuffix which represents different meaning depending on the key.

§Examples

use icu::locale::{
    extensions::unicode::{subdivision_suffix, SubdivisionId},
    subtags::region,
};

let ss = subdivision_suffix!("zzzz");
let region = region!("gb");

let si = SubdivisionId::new(region, ss);

assert_eq!(si.to_string(), "gbzzzz");

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§region: Region

A region field of a Subdivision Id.

§suffix: SubdivisionSuffix

A subdivision suffix field of a Subdivision Id.

Implementations§

§

impl SubdivisionId

pub const fn new(region: Region, suffix: SubdivisionSuffix) -> SubdivisionId

Returns a new SubdivisionId.

§Examples
use icu::locale::{
    extensions::unicode::{subdivision_suffix, SubdivisionId},
    subtags::region,
};

let ss = subdivision_suffix!("zzzz");
let region = region!("gb");

let si = SubdivisionId::new(region, ss);

assert_eq!(si.to_string(), "gbzzzz");

pub fn try_from_str(s: &str) -> Result<SubdivisionId, ParseError>

A constructor which takes a str slice, parses it and produces a well-formed SubdivisionId.

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

pub fn into_subtag(self) -> Subtag

Convert to Subtag

§

impl SubdivisionId

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.

impl Writeable for SubdivisionId

§

fn write_to<W>(&self, sink: &mut W) -> Result<(), Error>
