ForegroundExecutor

Struct ForegroundExecutor 

Source
pub struct ForegroundExecutor { /* private fields */ }
Expand description

A pointer to the executor that is currently running, for spawning tasks on the main thread.

This is intentionally !Send via the not_send marker field. This is because ForegroundExecutor::spawn does not require Send but checks at runtime that the future is only polled from the same thread it was spawned from. These checks would fail when spawning foreground tasks from background threads.

Implementations§

Source§

impl ForegroundExecutor

ForegroundExecutor runs things on the main thread.

Source

pub fn new(dispatcher: Arc<dyn PlatformDispatcher>) -> Self

Creates a new ForegroundExecutor from the given PlatformDispatcher.

Source

pub fn spawn<R>(&self, future: impl Future<Output = R> + 'static) -> Task<R>
where R: 'static,

Enqueues the given Task to run on the main thread at some point in the future.

Source

pub fn spawn_with_priority<R>( &self, priority: Priority, future: impl Future<Output = R> + 'static, ) -> Task<R>
where R: 'static,

Enqueues the given Task to run on the main thread at some point in the future.
