Trait futures_util::task::LocalSpawn
source · pub trait LocalSpawn {
// Required method
fn spawn_local_obj(
&self,
future: LocalFutureObj<'static, ()>
) -> Result<(), SpawnError>;
// Provided method
fn status_local(&self) -> Result<(), SpawnError> { ... }
}Expand description
The LocalSpawn is similar to Spawn, but allows spawning futures
that don’t implement Send.
Required Methods§
sourcefn spawn_local_obj(
&self,
future: LocalFutureObj<'static, ()>
) -> Result<(), SpawnError>
fn spawn_local_obj( &self, future: LocalFutureObj<'static, ()> ) -> Result<(), SpawnError>
Spawns a future that will be run to completion.
Errors
The executor may be unable to spawn tasks. Spawn errors should represent relatively rare scenarios, such as the executor having been shut down so that it is no longer able to accept tasks.
Provided Methods§
sourcefn status_local(&self) -> Result<(), SpawnError>
fn status_local(&self) -> Result<(), SpawnError>
Determines whether the executor is able to spawn new tasks.
This method will return Ok when the executor is likely
(but not guaranteed) to accept a subsequent spawn attempt.
Likewise, an Err return means that spawn is likely, but
not guaranteed, to yield an error.
