Struct icu::locid::extensions::Unicode

pub struct Unicode {
    pub keywords: Keywords,
    pub attributes: Attributes,
}

Unicode Extensions provide information about user preferences in a given locale.

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

Unicode extensions provide subtags that specify language and/or locale-based behavior or refinements to language tags, according to work done by the Unicode Consortium. (See RFC 6067 for details).

Examples

use icu::locid::Locale;
use icu::locid::extensions::unicode::{Key, Value};

let mut loc: Locale = "de-u-hc-h12-ca-buddhist".parse()
    .expect("Parsing failed.");

let key: Key = "ca".parse().expect("Parsing key failed.");
let value: Value = "buddhist".parse().expect("Parsing value failed.");
assert_eq!(loc.extensions.unicode.keywords.get(key),
           Some(&value));

Fields

keywords: Keywords

attributes: Attributes

Implementations

impl Unicode

pub const fn new() -> Unicode

Returns a new empty map of Unicode extensions. Same as default(), but is const.

Examples

use icu::locid::extensions::unicode::Unicode;

assert_eq!(Unicode::new(), Unicode::default());

pub fn is_empty(&self) -> bool

Returns true if there list of keywords and attributes is empty.

Examples

use icu::locid::Locale;

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

assert_eq!(loc.extensions.unicode.is_empty(), false);

Trait Implementations

pub fn clone(&self) -> Unicode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Unicode

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

Formats the value using the given formatter.

impl Default for Unicode

pub fn default() -> Unicode

Returns the “default value” for a type.

impl Display for Unicode

impl Eq for Unicode

impl Hash for Unicode

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

Feeds this value into the given Hasher.

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

Feeds a slice of this type into the given Hasher.

impl Ord for Unicode

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

This method returns an Ordering between self and other.

#[must_use]

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

Compares and returns the maximum of two values.

#[must_use]

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

Compares and returns the minimum of two values.

#[must_use]

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

Restrict a value to a certain interval.

impl PartialEq<Unicode> for Unicode

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

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

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

This method tests for !=.

impl PartialOrd<Unicode> for Unicode

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

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

#[must_use]

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

impl StructuralEq for Unicode

impl StructuralPartialEq for Unicode

impl Writeable for Unicode

pub fn write_to<W>(&self, sink: &mut W) -> Result<(), Error> where
    W: Write + ?Sized, 

Writes bytes to the given sink. Errors from the sink are bubbled up.

pub fn write_len(&self) -> LengthHint

Returns a hint for the number of bytes that will be written to the sink.

pub fn writeable_to_string(&self) -> String

Creates a new String with the data from this Writeable. Like ToString, but smaller and faster.
