pub struct TransformExtensionList { /* private fields */ }
Expand description

A list of Unicode BCP47 T Extensions as defined in Unicode Locale Identifier specification.

Transform extension carries information about source language or script of transformed content, including content that has been transliterated, transcribed, or translated, or in some other way influenced by the source (See RFC 6497 for details).

§Examples

use unic_locale_impl::{Locale, LanguageIdentifier};

let mut loc: Locale = "de-t-en-US-h0-hybrid".parse()
    .expect("Parsing failed.");

let en_us: LanguageIdentifier = "en-US".parse()
    .expect("Parsing failed.");

assert_eq!(loc.extensions.transform.tlang(), Some(&en_us));
assert_eq!(
    loc.extensions.transform.tfield("h0")
                            .expect("Getting tfield failed.")
                            .collect::<Vec<_>>(),
    &["hybrid"]
);

Implementations§

               .collect::<Vec<_>>(),
           &["dvorak"]);

source

pub fn set_tfield<S: AsRef<[u8]>>( &mut self, tkey: S, tvalue: &[S] ) -> Result<(), LocaleError>

Adds a tfield to the TransformExtensionList or sets tvalue for tkey if tfield is already included in the TransformExtensionList.

§Examples
use unic_locale_impl::Locale;

let mut loc: Locale = "en-US".parse()
    .expect("Parsing failed.");

loc.extensions.transform.set_tfield("k0", &["dvorak"])
    .expect("Setting tfield failed.");

assert_eq!(loc.to_string(), "en-US-t-k0-dvorak");

loc.extensions.transform.set_tfield("k0", &["colemak"])
    .expect("Setting tfield failed.");

assert_eq!(loc.to_string(), "en-US-t-k0-colemak");
source

pub fn remove_tfield<S: AsRef<[u8]>>( &mut self, tkey: S ) -> Result<bool, LocaleError>

Removes a tfield from the TransformExtensionList.

Returns true if tfield was included in the TransformExtensionList before removal.

§Examples
use unic_locale_impl::Locale;

let mut loc: Locale = "en-US-t-k0-dvorak".parse()
    .expect("Parsing failed.");

assert_eq!(loc.extensions.transform.remove_tfield("k0")
               .expect("Removing tfield failed."),
           true);

assert_eq!(loc.to_string(), "en-US");
source

pub fn clear_tfields(&mut self)

Clears all tfields from the TransformExtensionList.

§Examples
use unic_locale_impl::Locale;

let mut loc: Locale = "en-US-t-k0-dvorak".parse()
    .expect("Parsing failed.");

loc.extensions.transform.clear_tfields();
assert_eq!(loc.to_string(), "en-US");
