Methods from Deref<Target = Object>§
sourcepub fn has_own_property(&self, property: &JsValue) -> bool
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).
sourcepub fn is_prototype_of(&self, value: &JsValue) -> bool
pub fn is_prototype_of(&self, value: &JsValue) -> bool
The isPrototypeOf()
method checks if an object exists in another
object’s prototype chain.
sourcepub fn property_is_enumerable(&self, property: &JsValue) -> bool
pub fn property_is_enumerable(&self, property: &JsValue) -> bool
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
sourcepub fn to_locale_string(&self) -> JsString
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.
Methods from Deref<Target = JsValue>§
pub const NULL: JsValue = JsValue{ idx: JSIDX_NULL, _marker: marker::PhantomData,}
pub const UNDEFINED: JsValue = JsValue{ idx: JSIDX_UNDEFINED, _marker: marker::PhantomData,}
pub const TRUE: JsValue = JsValue{ idx: JSIDX_TRUE, _marker: marker::PhantomData,}
pub const FALSE: JsValue = JsValue{ idx: JSIDX_FALSE, _marker: marker::PhantomData,}
sourcepub fn as_f64(&self) -> Option<f64>
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
.
sourcepub fn as_string(&self) -> Option<String>
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
.
sourcepub fn as_bool(&self) -> Option<bool>
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
.
sourcepub fn is_undefined(&self) -> bool
pub fn is_undefined(&self) -> bool
Tests whether this JS value is undefined
sourcepub fn is_function(&self) -> bool
pub fn is_function(&self) -> bool
Tests whether the type of this JS value is function
.
