Struct `Attributes`

struct Attributes(_)

A set of Attribute elements as defined in Unicode Extension Attributes.

Examples

use icu::locale::extensions::unicode::{Attribute, Attributes};

let attribute1: Attribute =
    "foobar".parse().expect("Failed to parse a variant subtag.");

let attribute2: Attribute = "testing"
    .parse()
    .expect("Failed to parse a variant subtag.");
let mut v = vec![attribute1, attribute2];
v.sort();
v.dedup();

let attributes: Attributes = Attributes::from_vec_unchecked(v);
assert_eq!(attributes.to_string(), "foobar-testing");

Implementations

`impl Attributes`

fn to_string(self: &Self) -> String

Converts the given value to a String.

Under the hood, this uses an efficient Writeable implementation. However, in order to avoid allocating a string, it is more efficient to use Writeable directly.

`impl Attributes`

const fn new() -> Self

Returns a new empty set of attributes. Same as default(), but is const.

Examples

use icu::locale::extensions::unicode::Attributes;

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

fn clear(self: &mut Self) -> Self

Empties the Attributes list.

Returns the old list.

Examples

use icu::locale::extensions::unicode::{attribute, Attributes};
use writeable::assert_writeable_eq;

let mut attributes = Attributes::from_vec_unchecked(vec![
    attribute!("foobar"),
    attribute!("testing"),
]);

assert_writeable_eq!(attributes, "foobar-testing");

attributes.clear();

assert_writeable_eq!(attributes, "");
