Struct wayland_server::DataInit

pub struct DataInit<'a, D: 'static> { /* private fields */ }

Helper to initialize client-created objects

This helper is provided to you in your Dispatch and GlobalDispatch to initialize objects created by the client, by assigning them their user-data (or ObjectData if you need to go this lower-level route).

This step is mandatory, and failing to initialize a newly created object will cause a panic.

Implementations

impl<'a, D> DataInit<'a, D>

pub fn init<I: Resource + 'static, U: Send + Sync + 'static>( &mut self, resource: New<I>, data: U, ) -> I

where D: Dispatch<I, U> + 'static,

Initialize an object by assigning it its user-data

pub fn custom_init<I: Resource + 'static>( &mut self, resource: New<I>, data: Arc<dyn ObjectData<D>>, ) -> I

Set a custom ObjectData for this object

This object data is not managed by wayland-server, as a result you will not be able to retreive it through Resource::data(). Instead, you’ll need to retrieve it using Resource::object_data() and handle the downcasting yourself.

pub fn post_error<I: Resource + 'static>( &mut self, _resource: New<I>, code: impl Into<u32>, error: impl Into<String>, )

Post an error on an uninitialized object.

This is only meant to be used in GlobalDispatch where a global protocol object is instantiated.

Trait Implementations

impl<'a, D: Debug + 'static> Debug for DataInit<'a, D>

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

Formats the value using the given formatter.
