Struct unic_locale::extensions::PrivateExtensionList

pub struct PrivateExtensionList(/* private fields */);

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

impl PrivateExtensionList

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);

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);

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"]);

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");

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");

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");

Trait Implementations

impl Clone for PrivateExtensionList

fn clone(&self) -> PrivateExtensionList

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrivateExtensionList

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for PrivateExtensionList

fn default() -> PrivateExtensionList

Returns the “default value” for a type.

impl Display for PrivateExtensionList

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for PrivateExtensionList

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PrivateExtensionList

fn cmp(&self, other: &PrivateExtensionList) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for PrivateExtensionList

fn eq(&self, other: &PrivateExtensionList) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PrivateExtensionList

fn partial_cmp(&self, other: &PrivateExtensionList) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
