Struct icu_locid::extensions::Extensions

pub struct Extensions {
    pub unicode: Unicode,
    pub transform: Transform,
    pub private: Private,
}

A map of extensions associated with a given Locale.

Fields

unicode: Unicode

transform: Transform

private: Private

Implementations

impl Extensions

pub const fn new() -> Self

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

Examples

use icu::locid::extensions::Extensions;

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

pub fn is_empty(&self) -> bool

Returns whether there are no extensions present.

Examples

use icu::locid::Locale;

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

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

Trait Implementations

impl Clone for Extensions

fn clone(&self) -> Extensions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Extensions

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

Formats the value using the given formatter.

impl Default for Extensions

fn default() -> Extensions

Returns the “default value” for a type.

impl Display for Extensions

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

impl Eq for Extensions

impl Hash for Extensions

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

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 Extensions

fn cmp(&self, other: &Extensions) -> 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<Extensions> for Extensions

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

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

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

This method tests for !=.

impl PartialOrd<Extensions> for Extensions

fn partial_cmp(&self, other: &Extensions) -> 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

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

impl StructuralEq for Extensions

impl StructuralPartialEq for Extensions

impl Writeable for Extensions

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

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

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.
