Struct nannou::app::Proxy

pub struct Proxy { /* fields omitted */ }

A handle to the App that can be shared across threads. This may be used to “wake up” the App’s inner event loop.

Implementations

impl Proxy

pub fn wakeup(&self) -> Result<(), EventLoopClosed<()>>

Wake up the application!

This wakes up the App’s inner event loop and causes a user event to be emitted by the event loop.

The app::Proxy stores a flag in order to track whether or not the EventLoop is currently blocking and waiting for events. This method will only call the underlying winit::event_loop::EventLoopProxy::send_event method if this flag is set to true and will immediately set the flag to false afterwards. This makes it safe to call the wakeup method as frequently as necessary across methods without causing any underlying OS methods to be called more than necessary.
