Struct LocalScopeSpawner 

pub struct LocalScopeSpawner<'sc, T> { /* private fields */ }

A spawner that can be obtained from LocalScope::spawner.

This spawner may live longer then the scope. In case a future is spawned after the scope has been canceled or dropped, the spawner will return SpawnError::shutdown.

Implementations

impl<'sc, T> LocalScopeSpawner<'sc, T>

pub fn spawn_scoped_local_obj( &self, future: LocalFutureObj<'sc, T>, ) -> Result<(), SpawnError>

Spawns a task that polls the given local future.

Errors

This method returns a Result that contains a SpawnError if spawning fails.

pub fn spawn_local_scoped<Fut>(&self, future: Fut) -> Result<(), SpawnError>

where Fut: Future<Output = T> + 'sc,

Spawns a task that polls the given local future.

Errors

This method returns a Result that contains a SpawnError if spawning fails.

impl<'sc> LocalScopeSpawner<'sc, ()>

pub fn spawn_local_scoped_with_handle<Fut>( &self, future: Fut, ) -> Result<RemoteHandle<Fut::Output>, SpawnError>

where Fut: Future + 'sc,

Spawns a task that polls the given local future and returns a handle to its output.

Errors

This method returns a Result that contains a SpawnError if spawning fails.
