A trait representing the handling of new bound globals

Required Methods

fn bind( self: Arc<Self>, handle: &Handle, data: &mut D, client_id: ClientId, global_id: GlobalId, object_id: ObjectId, ) -> Arc<dyn ObjectData<D>>

A global has been bound

Given client bound given global, creating given object.

The method must return the object data for the newly created object.

Provided Methods

fn can_view( &self, _client_id: ClientId, _client_data: &Arc<dyn ClientData>, _global_id: GlobalId, ) -> bool

Check if given client is allowed to interact with given global

If this function returns false, the client will not be notified of the existence of this global, and any attempt to bind it will result in a protocol error as if the global did not exist.

Default implementation always return true.

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

Helper for forwarding a Debug implementation of your GlobalHandler type

By default will just print GlobalHandler { ... }

Trait Implementations

impl<D> Debug for dyn GlobalHandler<D>

where D: 'static,

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

Formats the value using the given formatter.
