Methods from Deref<Target = Object>
The constructor property returns a reference to the Object
constructor
function that created the instance object.
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
The isPrototypeOf()
method checks if an object exists in another
object’s prototype chain.
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
The toString()
method returns a string representing the object.
The valueOf()
method returns the primitive value of the
specified object.
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
.
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 undefined
Tests whether the type of this JS value is function
.
Applies the unary typeof
JS operator on a JsValue
.
Applies the binary in
JS operator on the two JsValue
s.
Compare two JsValue
s for equality, using the ==
operator in JS.
Applies the unary ~
JS operator on a JsValue
.
Applies the binary >>>
JS operator on the two JsValue
s.
Applies the binary /
JS operator on two JsValue
s, catching and returning any RangeError
thrown.
Applies the binary **
JS operator on the two JsValue
s.
Applies the binary <
JS operator on the two JsValue
s.
Applies the binary <=
JS operator on the two JsValue
s.
Applies the binary >=
JS operator on the two JsValue
s.
Applies the binary >
JS operator on the two JsValue
s.
Applies the unary +
JS operator on a JsValue
. Can throw.
