Struct rusty_v8::Set

#[repr(C)]pub struct Set(_);

An instance of the built-in Set constructor (ECMA-262, 6th Edition, 23.2.1).

Methods from Deref<Target = Object>

pub fn set(
    &self,
    scope: &mut HandleScope,
    key: Local<Value>,
    value: Local<Value>
) -> Option<bool>

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

pub fn set_index(
    &self,
    scope: &mut HandleScope,
    index: u32,
    value: Local<Value>
) -> Option<bool>

Set only return Just(true) or Empty(), so if it should never fail, use result.Check().

pub fn set_prototype(
    &self,
    scope: &mut HandleScope,
    prototype: Local<Value>
) -> Option<bool>

Set the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.

pub fn create_data_property(
    &self,
    scope: &mut HandleScope,
    key: Local<Name>,
    value: Local<Value>
) -> Option<bool>

Implements CreateDataProperty (ECMA-262, 7.3.4).

Defines a configurable, writable, enumerable property with the given value on the object unless the property already exists and is not configurable or the object is not extensible.

Returns true on success.

pub fn define_own_property(
    &self,
    scope: &mut HandleScope,
    key: Local<Name>,
    value: Local<Value>,
    attr: PropertyAttribute
) -> Option<bool>

Implements DefineOwnProperty.

In general, CreateDataProperty will be faster, however, does not allow for specifying attributes.

Returns true on success.

pub fn get<'s>(
    &self,
    scope: &mut HandleScope<'s>,
    key: Local<Value>
) -> Option<Local<'s, Value>>

pub fn get_index<'s>(
    &self,
    scope: &mut HandleScope<'s>,
    index: u32
) -> Option<Local<'s, Value>>

pub fn get_prototype<'s>(
    &self,
    scope: &mut HandleScope<'s>
) -> Option<Local<'s, Value>>

Get the prototype object. This does not skip objects marked to be skipped by proto and it does not consult the security handler.

pub fn set_accessor(
    &self,
    scope: &mut HandleScope,
    name: Local<Name>,
    getter: impl for<'s> MapFnTo<AccessorNameGetterCallback<'s>>
) -> Option<bool>

Note: SideEffectType affects the getter only, not the setter.

pub fn get_identity_hash(&self) -> int

Returns the identity hash for this object. The current implementation uses a hidden property on the object to store the identity hash.

The return value will never be 0. Also, it is not guaranteed to be unique.

pub fn creation_context<'s>(
    &self,
    scope: &mut HandleScope<'s>
) -> Local<'s, Context>

Returns the context in which the object was created.

pub fn get_own_property_names<'s>(
    &self,
    scope: &mut HandleScope<'s>
) -> Option<Local<'s, Array>>

This function has the same functionality as GetPropertyNames but the returned array doesn't contain the names of properties from prototype objects.

pub fn get_property_names<'s>(
    &self,
    scope: &mut HandleScope<'s>
) -> Option<Local<'s, Array>>

Returns an array containing the names of the filtered properties of this object, including properties from prototype objects. The array returned by this method contains the same values as would be enumerated by a for-in statement over this object.

impl Deref for Set

type Target = Object

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
