    AppMessage: Message,
{ /* private fields */ }
Expand description

An application that is not yet running.

Implementations§

source§

impl PendingApp<()>

source

pub fn new() -> Self

Returns a new app with no windows. If no windows are opened before the app is run, the app will immediately close.

source§

impl<AppMessage> PendingApp<AppMessage>
where AppMessage: Message,

source

pub fn new_with_event_callback( event_callback: impl FnMut(AppMessage, &Windows<AppMessage::Window>) -> AppMessage::Response + 'static ) -> Self

Returns a new app with no windows. If no windows are opened before the app is run, the app will immediately close.

source

pub fn run(self) -> Result<(), EventLoopError>

Begins running the application.

Internally this runs the EventLoop.

§Errors

Returns an EventLoopError upon the loop exiting due to an error. See EventLoop::run for more information.

fn app(&self) -> App<AppMessage>

Returns a handle to the running application.
source§

fn send( &mut self, message: AppMessage ) -> Option<<AppMessage as Message>::Response>

impl<T, AppMessage> AsApplication<AppMessage> for T
where T: Application<AppMessage>, AppMessage: Message,

source§

fn as_application(&self) -> &dyn Application<AppMessage>
where AppMessage: Message,

Returns this type’s application.

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§
