Expand description

A helper for global initialization.

§registry: WlRegistry

Implementations§

source§

impl GlobalList

source

pub fn contents(&self) -> &GlobalListContents

Access the contents of the list of globals

source

pub fn bind<I, State, U>( &self, qh: &QueueHandle<State>, version: RangeInclusive<u32>, udata: U, ) -> Result<I, BindError>
where I: Proxy + 'static, State: Dispatch<I, U> + 'static, U: Send + Sync + 'static,

Binds a global, returning a new protocol object associated with the global.

The version specifies the range of versions that should be bound. This function will guarantee the version of the returned protocol object is the lower of the maximum requested version and the advertised version.

If the lower bound of the version is less than the version advertised by the server, then BindError::UnsupportedVersion is returned.

§Multi-instance/Device globals.

This function is not intended to be used with globals that have multiple instances such as wl_output and wl_seat. These types of globals need their own initialization mechanism because these multi-instance globals may be removed at runtime. To handle then, you should instead rely on the Dispatch implementation for WlRegistry of your State.

§Panics

This function will panic if the maximum requested version is greater than the known maximum version of the interface. The known maximum version is determined by the code generated using wayland-scanner.

source

pub fn registry(&self) -> &WlRegistry

Returns the WlRegistry protocol object.

This may be used if more direct control when creating globals is needed.

impl<T> Downcast for T
where T: Any,

source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.
source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
