Struct unic_locale::extensions::PrivateExtensionList

source ·
pub struct PrivateExtensionList(/* private fields */);
Expand description

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

Those extensions are intended for pass-through use.

§Examples

use unic_locale_impl::Locale;

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

assert_eq!(loc.extensions.private.has_tag("faa"), Ok(true));
assert_eq!(loc.extensions.private.tags().next(), Some("faa")); // tags got sorted
loc.extensions.private.clear_tags();
assert_eq!(loc.to_string(), "en-US");

Implementations§

source§

impl PrivateExtensionList

source

pub fn is_empty(&self) -> bool

Returns true if there are no tags in the PrivateExtensionList`.

§Examples
use unic_locale_impl::Locale;

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

assert_eq!(loc.extensions.private.is_empty(), false);
source

pub fn has_tag<S>(&self, tag: S) -> Result<bool, LocaleError>
where S: AsRef<[u8]>,

Returns true if tag is included in the PrivateExtensionList.

§Examples
use unic_locale_impl::Locale;

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

assert_eq!(loc.extensions.private.has_tag("foo")
              .expect("Getting tag failed."),
           true);
source

pub fn tags(&self) -> impl ExactSizeIterator

Returns an iterator over all tags in the PrivateExtensionList.

§Examples
use unic_locale_impl::Locale;

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

assert_eq!(loc.extensions.private.tags().collect::<Vec<_>>(),
           &["bar", "foo"]);
source

pub fn add_tag<S>(&mut self, tag: S) -> Result<(), LocaleError>
where S: AsRef<[u8]>,

Adds a tag to the PrivateExtensionList.

§Examples
use unic_locale_impl::Locale;

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

loc.extensions.private.add_tag("foo")
    .expect("Adding tag failed.");

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

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

Removes a tag from the PrivateExtensionList.

Returns true if tag was included in the PrivateExtensionList before removal.

§Examples
use unic_locale_impl::Locale;

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

assert_eq!(loc.extensions.private.remove_tag("foo")
              .expect("Removing tag failed."),
           true);

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

pub fn clear_tags(&mut self)

Clears all tags from the PrivateExtensionList.

§Examples
use unic_locale_impl::Locale;

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

loc.extensions.private.clear_tags();
assert_eq!(loc.to_string(), "en-US");
