Trait representing a Wayland interface
Required Associated Types
Required Methods
Access the user-data associated with this object
fn object_data(&self) -> Option<&Arc<dyn ObjectData>>
fn object_data(&self) -> Option<&Arc<dyn ObjectData>>
Access the raw data associated with this object.
For objects created using the scanner-generated methods, this will be an instance of the QueueProxyData type.
fn backend(&self) -> &WeakBackend
fn backend(&self) -> &WeakBackend
Access the backend associated with this object
Create an object proxy from its ID
Returns an error this the provided object ID does not correspond to
the Self interface.
Note: This method is mostly meant as an implementation detail to be used by code generated by wayland-scanner.
Send a request for this object.
It is an error to use this function on requests that create objects; use Proxy::send_constructor for such requests.
fn send_constructor<I: Proxy>(
&self,
req: Self::Request,
data: Arc<dyn ObjectData>
) -> Result<I, InvalidId>
fn send_constructor<I: Proxy>(
&self,
req: Self::Request,
data: Arc<dyn ObjectData>
) -> Result<I, InvalidId>
Send a request for this object that creates another object.
It is an error to use this function on requests that do not create objects; use Proxy::send_request for such requests.
fn parse_event(
conn: &Connection,
msg: Message<ObjectId>
) -> Result<(Self, Self::Event), DispatchError>
fn parse_event(
conn: &Connection,
msg: Message<ObjectId>
) -> Result<(Self, Self::Event), DispatchError>
Parse a event for this object
