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
pub const UNDEFINED: JsValue
pub const TRUE: JsValue
pub const FALSE: JsValue
sourcepub fn into_serde<T>(&self) -> Result<T, Error> where
T: for<'a> Deserialize<'a>,
pub fn into_serde<T>(&self) -> Result<T, Error> where
T: for<'a> Deserialize<'a>,
Invokes JSON.stringify
on this value and then parses the resulting
JSON into an arbitrary Rust value.
This function will first call JSON.stringify
on the JsValue
itself.
The resulting string is then passed into Rust which then parses it as
JSON into the resulting value.
Usage of this API requires activating the serde-serialize
feature of
the wasm-bindgen
crate.
Errors
Returns any error encountered when parsing the JSON into a T
.
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

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

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.
