A trait representing your data associated to an object

You will only be given access to it as a & reference, so you need to handle interior mutability by yourself.

The methods of this trait will be invoked internally every time a new object is created to initialize its data.

Required Methods

fn request( self: Arc<Self>, handle: &Handle, data: &mut D, client_id: ClientId, msg: Message<ObjectId, OwnedFd>, ) -> Option<Arc<dyn ObjectData<D>>>

Dispatch a request for the associated object

If the request has a NewId argument, the callback must return the object data for the newly created object

fn destroyed( self: Arc<Self>, handle: &Handle, data: &mut D, client_id: ClientId, object_id: ObjectId, )

Notification that the object has been destroyed and is no longer active

Provided Methods

fn debug(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Helper for forwarding a Debug implementation of your ObjectData type

By default will just print ObjectData { ... }

Trait Implementations

impl<D> Debug for dyn ObjectData<D>

where D: 'static,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
