Implementations

impl AccessorDescriptor

pub fn new(
    get: Option<GcObject>,
    set: Option<GcObject>,
    mut attributes: Attribute
) -> Self

Create a new AccessorDescriptor.

If the attributes argument contains a writable flag, it will be removed so only enumerable and configurable remains.

pub fn getter(&self) -> Option<&GcObject>

Return the getter if it exists.

pub fn setter(&self) -> Option<&GcObject>

Return the setter if it exists.

pub fn set_getter(&mut self, get: Option<GcObject>)

Set the getter of the accessor descriptor.

pub fn set_setter(&mut self, set: Option<GcObject>)

Set the setter of the accessor descriptor.

pub fn attributes(&self) -> Attribute

Return the attributes of the accessor descriptor.

It is guaranteed to not contain a writable flag

pub fn configurable(&self) -> bool

Check whether the descriptor is configurable.

pub fn set_configurable(&mut self, configurable: bool)

Set whether the descriptor is configurable.

pub fn enumerable(&self) -> bool

Check whether the descriptor is enumerable.

pub fn set_enumerable(&mut self, enumerable: bool)

Set whether the descriptor is enumerable.
