Methods from Deref<Target = Object>

pub fn constructor(&self) -> Function[src]

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

MDN documentation

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

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

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

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

MDN documentation

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

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

MDN documentation

pub fn to_locale_string(&self) -> JsString[src]

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

pub fn to_string(&self) -> JsString[src]

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

MDN documentation

pub fn value_of(&self) -> Object[src]

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

MDN documentation

Methods from Deref<Target = JsValue>

pub const NULL: JsValue[src]

pub const UNDEFINED: JsValue[src]

pub const TRUE: JsValue[src]

pub const FALSE: JsValue[src]

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

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.

pub fn is_string(&self) -> bool[src]

Tests whether this JS value is a JS string.

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

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.

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

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.

pub fn is_null(&self) -> bool[src]

Tests whether this JS value is null

pub fn is_undefined(&self) -> bool[src]

Tests whether this JS value is undefined

pub fn is_symbol(&self) -> bool[src]

Tests whether the type of this JS value is symbol

pub fn is_object(&self) -> bool[src]

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

pub fn is_function(&self) -> bool[src]

Tests whether the type of this JS value is function.

pub fn is_truthy(&self) -> bool[src]

Tests whether the value is “truthy”.

pub fn is_falsy(&self) -> bool[src]

Tests whether the value is “falsy”.
