Struct RuntimeSpawner 

pub struct RuntimeSpawner { /* private fields */ }

UI-thread-only helper that launches Tokio work with Incular owner tracking.

Implementations

impl RuntimeSpawner

pub fn spawn<F, T>(&self, future: F) -> Task<T>

where F: Future<Output = T> + Send + 'static, T: Send + 'static,

Starts application-scoped Tokio work. Its output is observed through the returned state handle; use spawn_into to update UI-local state.

pub fn spawn_in<F, T>(&self, scope: &TaskScope, future: F) -> Task<T>

where F: Future<Output = T> + Send + 'static, T: Send + 'static,

pub fn spawn_into<F, T>( &self, future: F, complete: impl FnOnce(Result<T, TaskFailure>, &mut Runtime) + 'static, ) -> TaskHandle

where F: Future<Output = T> + Send + 'static, T: Send + 'static,

Starts Tokio work and invokes complete later on the UI thread. The callback may capture non-Send Signals because only the Send output crosses the Tokio/UI boundary.

pub fn spawn_into_in<F, T>( &self, scope: &TaskScope, future: F, complete: impl FnOnce(Result<T, TaskFailure>, &mut Runtime) + 'static, ) -> TaskHandle

where F: Future<Output = T> + Send + 'static, T: Send + 'static,

pub fn spawn_blocking<T>( &self, work: impl FnOnce() -> T + Send + 'static, complete: impl FnOnce(Result<T, TaskFailure>, &mut Runtime) + 'static, ) -> TaskHandle

where T: Send + 'static,

Submits work to Tokio’s blocking facility. A cancellation after work begins is represented as an uninterested/discarded UI completion.

pub fn spawn_blocking_in<T>( &self, scope: &TaskScope, work: impl FnOnce() -> T + Send + 'static, complete: impl FnOnce(Result<T, TaskFailure>, &mut Runtime) + 'static, ) -> TaskHandle

where T: Send + 'static,

pub fn scope(&self) -> TaskScope

pub fn tokio_handle(&self) -> TokioHandle

pub fn dispatcher(&self) -> UiDispatcher
