Methods from Deref<Target = Object>
sourcepub fn constructor(&self) -> Function
pub fn constructor(&self) -> Function
The constructor property returns a reference to the Object
constructor
function that created the instance 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
.
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.
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
.
sourcepub fn js_in(&self, obj: &JsValue) -> bool
pub fn js_in(&self, obj: &JsValue) -> bool
Applies the binary in
JS operator on the two JsValue
s.
sourcepub fn loose_eq(&self, other: &JsValue) -> bool
pub fn loose_eq(&self, other: &JsValue) -> bool
Compare two JsValue
s for equality, using the ==
operator in JS.
sourcepub fn unsigned_shr(&self, rhs: &JsValue) -> u32
pub fn unsigned_shr(&self, rhs: &JsValue) -> u32
Applies the binary >>>
JS operator on the two JsValue
s.
sourcepub fn checked_div(&self, rhs: &JsValue) -> JsValue
pub fn checked_div(&self, rhs: &JsValue) -> JsValue
Applies the binary /
JS operator on two JsValue
s, catching and returning any RangeError
thrown.
sourcepub fn pow(&self, rhs: &JsValue) -> JsValue
pub fn pow(&self, rhs: &JsValue) -> JsValue
Applies the binary **
JS operator on the two JsValue
s.
sourcepub fn lt(&self, other: &JsValue) -> bool
pub fn lt(&self, other: &JsValue) -> bool
Applies the binary <
JS operator on the two JsValue
s.
sourcepub fn le(&self, other: &JsValue) -> bool
pub fn le(&self, other: &JsValue) -> bool
Applies the binary <=
JS operator on the two JsValue
s.
sourcepub fn ge(&self, other: &JsValue) -> bool
pub fn ge(&self, other: &JsValue) -> bool
Applies the binary >=
JS operator on the two JsValue
s.
sourcepub fn gt(&self, other: &JsValue) -> bool
pub fn gt(&self, other: &JsValue) -> bool
Applies the binary >
JS operator on the two JsValue
s.
sourcepub fn unchecked_into_f64(&self) -> f64
pub fn unchecked_into_f64(&self) -> f64
Applies the unary +
JS operator on a JsValue
. Can throw.
