Implementations§

source§

impl DateTimeFormat

source

pub fn new(locales: &Array, options: &Object) -> DateTimeFormat

The Intl.DateTimeFormat object is a constructor for objects that enable language-sensitive date and time formatting.

MDN documentation

source§

impl DateTimeFormat

source

pub fn format(&self) -> Function

The Intl.DateTimeFormat.prototype.format property returns a getter function that formats a date according to the locale and formatting options of this Intl.DateTimeFormat object.

MDN documentation

source§

impl DateTimeFormat

source

pub fn format_to_parts(&self, date: &Date) -> Array

The Intl.DateTimeFormat.prototype.formatToParts() method allows locale-aware formatting of strings produced by DateTimeFormat formatters.

MDN documentation

source§

impl DateTimeFormat

source

pub fn resolved_options(&self) -> Object

The Intl.DateTimeFormat.prototype.resolvedOptions() method returns a new object with properties reflecting the locale and date and time formatting options computed during initialization of this DateTimeFormat object.

MDN documentation

source§

impl DateTimeFormat

source

pub fn supported_locales_of(locales: &Array, options: &Object) -> Array

The Intl.DateTimeFormat.supportedLocalesOf() method returns an array containing those of the provided locales that are supported in date and time formatting without having to fall back to the runtime’s default locale.

MDN documentation

Methods from Deref<Target = Object>§

source

pub fn constructor(&self) -> Function

The constructor property returns a reference to the Object constructor function that created the instance object.

MDN documentation

source

pub fn has_own_property(&self, property: &JsValue) -> bool

The hasOwnProperty() method returns a boolean indicating whether the object has the specified property as its own property (as opposed to inheriting it).

MDN documentation

source

pub fn is_prototype_of(&self, value: &JsValue) -> bool

The isPrototypeOf() method checks if an object exists in another object’s prototype chain.

MDN documentation

source

pub fn property_is_enumerable(&self, property: &JsValue) -> bool

The propertyIsEnumerable() method returns a Boolean indicating whether the specified property is enumerable.

MDN documentation

source

pub fn to_locale_string(&self) -> JsString

The toLocaleString() method returns a string representing the object. This method is meant to be overridden by derived objects for locale-specific purposes.

MDN documentation

source

pub fn to_string(&self) -> JsString

The toString() method returns a string representing the object.

MDN documentation

source

pub fn value_of(&self) -> Object

The valueOf() method returns the primitive value of the specified object.

MDN documentation

Methods from Deref<Target = JsValue>§

source

pub const NULL: JsValue = _

source

pub const UNDEFINED: JsValue = _

source

pub const TRUE: JsValue = _

source

pub const FALSE: JsValue = _

source

pub fn as_f64(&self) -> Option<f64>

Returns the f64 value of this JS value if it’s an instance of a number.

If this JS value is not an instance of a number then this returns None.

source

pub fn is_string(&self) -> bool

Tests whether this JS value is a JS string.

source

pub fn as_string(&self) -> Option<String>

If this JS value is a string value, this function copies the JS string value into Wasm linear memory, encoded as UTF-8, and returns it as a Rust String.

To avoid the copying and re-encoding, consider the JsString::try_from() function from js-sys instead.

If this JS value is not an instance of a string or if it’s not valid utf-8 then this returns None.

§UTF-16 vs UTF-8

JavaScript strings in general are encoded as UTF-16, but Rust strings are encoded as UTF-8. This can cause the Rust string to look a bit different than the JS string sometimes. For more details see the documentation about the str type which contains a few caveats about the encodings.

source

pub fn as_bool(&self) -> Option<bool>

Returns the bool value of this JS value if it’s an instance of a boolean.

If this JS value is not an instance of a boolean then this returns None.

source

Tests whether this JS value is null

source

pub fn is_undefined(&self) -> bool

Tests whether this JS value is undefined

source

pub fn is_symbol(&self) -> bool

Tests whether the type of this JS value is symbol

source

pub fn is_object(&self) -> bool

Tests whether typeof self == "object" && self !== null.

source

pub fn is_array(&self) -> bool

Tests whether this JS value is an instance of Array.

source

pub fn is_function(&self) -> bool

Tests whether the type of this JS value is function.

source

pub fn is_bigint(&self) -> bool

Tests whether the type of this JS value is bigint.

source

pub fn js_typeof(&self) -> JsValue
