Implementations
impl Set
[src]
pub fn add(&self, value: &JsValue) -> Set
[src]
The add()
method appends a new element with a specified value to the
end of a Set
object.
impl Set
[src]
impl Set
[src]
pub fn delete(&self, value: &JsValue) -> bool
[src]
The delete()
method removes the specified element from a Set
object.
impl Set
[src]
pub fn for_each(&self, callback: &mut dyn FnMut(JsValue, JsValue, Set))
[src]
The forEach()
method executes a provided function once for each value
in the Set object, in insertion order.
impl Set
[src]
pub fn has(&self, value: &JsValue) -> bool
[src]
The has()
method returns a boolean indicating whether an element with
the specified value exists in a Set
object or not.
impl Set
[src]
pub fn new(init: &JsValue) -> Set
[src]
The Set
object lets you store unique values of any type, whether
primitive values or object references.
impl Set
[src]
pub fn size(&self) -> u32
[src]
The size accessor property returns the number of elements in a Set
object.
impl Set
[src]
pub fn entries(&self) -> Iterator
[src]
The entries()
method returns a new Iterator object that contains an
array of [value, value] for each element in the Set object, in insertion
order. For Set objects there is no key like in Map objects. However, to
keep the API similar to the Map object, each entry has the same value
for its key and value here, so that an array [value, value] is returned.
impl Set
[src]
pub fn keys(&self) -> Iterator
[src]
The keys()
method is an alias for this method (for similarity with
Map objects); it behaves exactly the same and returns values
of Set elements.
impl Set
[src]
pub fn values(&self) -> Iterator
[src]
The values()
method returns a new Iterator object that contains the
values for each element in the Set object in insertion order.
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 into_serde<T>(&self) -> Result<T, Error> where
T: for<'a> Deserialize<'a>,
[src]
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
.
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".
