Struct TaskExecutor

pub struct TaskExecutor { /* private fields */ }

Executes futures on the current thread.

All futures executed using this executor will be executed on the current thread. As such, run will wait for these futures to complete before returning.

For more details, see the module level documentation.

Implementations

impl TaskExecutor

pub fn current() -> TaskExecutor

Returns an executor that executes futures on the current thread.

pub fn spawn_local( &mut self, future: Box<dyn Future<Item = (), Error = ()>>, ) -> Result<(), SpawnError>

Spawn a future onto the current CurrentThread instance.
