Struct Other 

pub struct Other {
    ext: u8,
    keys: ShortBoxSlice<Subtag>,
}

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

Those extensions are treated as a pass-through, and no Unicode related behavior depends on them.

Examples

use icu::locale::extensions::other::Other;
use icu::locale::subtags::Subtag;

let subtag1: Subtag = "foo".parse().expect("Failed to parse a Subtag.");
let subtag2: Subtag = "bar".parse().expect("Failed to parse a Subtag.");

let other = Other::from_vec_unchecked(b'a', vec![subtag1, subtag2]);
assert_eq!(&other.to_string(), "a-foo-bar");

Fields

ext: u8

keys: ShortBoxSlice<Subtag>

Implementations

impl Other

pub fn try_from_str(s: &str) -> Result<Self, ParseError>

A constructor which takes a str slice, parses it and produces a well-formed Other.

✨ Enabled with the alloc Cargo feature.

pub fn try_from_utf8(code_units: &[u8]) -> Result<Self, ParseError>

See Self::try_from_str

✨ Enabled with the alloc Cargo feature.

pub fn from_vec_unchecked(ext: u8, keys: Vec<Subtag>) -> Self

A constructor which takes a pre-sorted list of Subtag.

✨ Enabled with the alloc Cargo feature.

Panics

Panics if ext is not ASCII alphanumeric.

Examples

use icu::locale::extensions::other::Other;
use icu::locale::subtags::Subtag;

let subtag1: Subtag = "foo".parse().expect("Failed to parse a Subtag.");
let subtag2: Subtag = "bar".parse().expect("Failed to parse a Subtag.");

let other = Other::from_vec_unchecked(b'a', vec![subtag1, subtag2]);
assert_eq!(&other.to_string(), "a-foo-bar");

pub(crate) fn from_short_slice_unchecked( ext: u8, keys: ShortBoxSlice<Subtag>, ) -> Self

pub(crate) fn try_from_iter( ext: u8, iter: &mut SubtagIterator<'_>, ) -> Result<Self, ParseError>

pub fn get_ext_str(&self) -> &str

Gets the tag character for this extension as a &str.

Examples

use icu::locale::Locale;

let loc: Locale = "und-a-hello-world".parse().unwrap();
let other_ext = &loc.extensions.other[0];
assert_eq!(other_ext.get_ext_str(), "a");

pub fn get_ext(&self) -> char

Gets the tag character for this extension as a char.

Examples

use icu::locale::Locale;

let loc: Locale = "und-a-hello-world".parse().unwrap();
let other_ext = &loc.extensions.other[0];
assert_eq!(other_ext.get_ext(), 'a');

pub fn get_ext_byte(&self) -> u8

Gets the tag character for this extension as a byte.

Examples

use icu::locale::Locale;

let loc: Locale = "und-a-hello-world".parse().unwrap();
let other_ext = &loc.extensions.other[0];
assert_eq!(other_ext.get_ext_byte(), b'a');

pub(crate) fn for_each_subtag_str<E, F>( &self, f: &mut F, with_ext: bool, ) -> Result<(), E>

where F: FnMut(&str) -> Result<(), E>,

impl Other

pub fn to_string(&self) -> String

Converts the given value to a String.

Under the hood, this uses an efficient [Writeable] implementation.

If you don’t need an allocated String, but e.g. need to write this to some sink, it is more efficient to use [Writeable] directly.

Trait Implementations

impl Clone for Other

fn clone(&self) -> Other

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Other

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

Formats the value using the given formatter.

impl Default for Other

fn default() -> Other

Returns the “default value” for a type.

impl Display for Other

This trait is implemented for compatibility with fmt!. To create a string, [Writeable::write_to_string] is usually more efficient.

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

Formats the value using the given formatter.

impl FromStr for Other

Available on crate feature alloc only.

✨ Enabled with the alloc Cargo feature.

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Other

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

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 Other

fn cmp(&self, other: &Other) -> 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,

Restrict a value to a certain interval.

impl PartialEq for Other

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for Other

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Writeable for Other

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

Writes a string to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to_parts, and discards any Part annotations.

fn writeable_length_hint(&self) -> LengthHint

Returns a hint for the number of UTF-8 bytes that will be written to the sink.

fn write_to_parts<S>(&self, sink: &mut S) -> Result<(), Error>

where S: PartsWrite + ?Sized,

Write bytes and Part annotations to the given sink. Errors from the sink are bubbled up. The default implementation delegates to write_to, and doesn’t produce any Part annotations.

fn writeable_borrow(&self) -> Option<&str>

Returns a &str that matches the output of write_to, if possible.

fn write_to_string(&self) -> Cow<'_, str>

Creates a new string with the data from this Writeable.
