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.
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).
pub fn is_prototype_of(&self, value: &JsValue) -> bool
[src]
The isPrototypeOf()
method checks if an object exists in another
object’s prototype chain.
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
[src]
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
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.
pub fn to_string(&self) -> JsString
[src]
The toString()
method returns a string representing the object.
pub fn value_of(&self) -> Object
[src]
The valueOf()
method returns the primitive value of the
specified object.
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”.
