Struct ApplicationHandle

Source

pub struct ApplicationHandle { /* private fields */ }

Expand description

A strong handle to an Application started with Application::run_embedded.

Dropping this handle releases the app, so an embedder must hold it for as long as the app should run. While held, it is the embedder’s entry point back into GPUI each time the external run loop gives it control.

Implementations§

Source §

impl ApplicationHandle

Source

pub fn update<R>(&self, f: impl FnOnce(&mut App) -> R) -> R

Invoke f with the app context. Must not be called re-entrantly from code that is already inside an update; the app state is a RefCell and will panic on a double borrow.

Source

pub fn to_async(&self) -> AsyncApp

An AsyncApp for use across await points. It holds the app weakly; keeping the app alive remains this handle’s job.
