Methods from Deref<Target = Object>§

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

MDN documentation

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

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

MDN documentation

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

MDN documentation

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

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

MDN documentation

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

MDN documentation

Methods from Deref<Target = JsValue>§

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.

Tests whether this JS value is a JS 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.

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.

Tests whether this JS value is null

Tests whether this JS value is undefined

Tests whether the type of this JS value is symbol

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

Tests whether the type of this JS value is function.

Tests whether the type of this JS value is bigint.

Applies the unary typeof JS operator on a JsValue.

MDN documentation

Applies the binary in JS operator on the two JsValues.

MDN documentation

Tests whether the value is “truthy”.

Tests whether the value is “falsy”.

Compare two JsValues for equality, using the == operator in JS.

MDN documentation

Applies the unary ~ JS operator on a JsValue.

MDN documentation

Applies the binary >>> JS operator on the two JsValues.

MDN documentation

Applies the binary / JS operator on two JsValues, catching and returning any RangeError thrown.

MDN documentation

Applies the binary ** JS operator on the two JsValues.

MDN documentation

Applies the binary < JS operator on the two JsValues.

MDN documentation

Applies the binary <= JS operator on the two JsValues.

MDN documentation

Applies the binary >= JS operator on the two JsValues.

MDN documentation

Applies the binary > JS operator on the two JsValues.

MDN documentation

Applies the unary + JS operator on a JsValue. Can throw.
