Trait wayland_server::backend::ClientData

pub trait ClientData: DowncastSync {
    fn initialized(&self, client_id: ClientId);
    fn disconnected(&self, client_id: ClientId, reason: DisconnectReason);

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

A trait representing your data associated to a clientObjectData

Required Methods

fn initialized(&self, client_id: ClientId)

Notification that the client was initialized

fn disconnected(&self, client_id: ClientId, reason: DisconnectReason)

Notification that the client is disconnected

Provided Methods

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

Helper for forwarding a Debug implementation of your ClientData type

By default will just print GlobalHandler { ... }

Implementations

impl dyn ClientData + 'static

pub fn is<__T>(&self) -> bool where
    __T: ClientData, 

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T>(
    self: Box<dyn ClientData + 'static, Global>
) -> Result<Box<__T, Global>, Box<dyn ClientData + 'static, Global>> where
    __T: ClientData, 

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T>(
    self: Rc<dyn ClientData + 'static>
) -> Result<Rc<__T>, Rc<dyn ClientData + 'static>> where
    __T: ClientData, 

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T>(&self) -> Option<&__T> where
    __T: ClientData, 

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T>(&mut self) -> Option<&mut __T> where
    __T: ClientData, 

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_arc<__T>(
    self: Arc<dyn ClientData + 'static>
) -> Result<Arc<__T>, Arc<dyn ClientData + 'static>> where
    __T: ClientData + Any + Send + Sync, 

Returns an Arc-ed object from an Arc-ed trait object if the underlying object is of type __T. Returns the original Arc-ed trait if it isn’t.

Trait Implementations

impl Debug for dyn ClientData + 'static

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

Formats the value using the given formatter.
