Trait futures_util::task::Spawn

pub trait Spawn {
    fn spawn_obj(
        &self, 
        future: FutureObj<'static, ()>
    ) -> Result<(), SpawnError>;

    fn status(&self) -> Result<(), SpawnError> { ... }
}

The Spawn trait allows for pushing futures onto an executor that will run them to completion.

Required methods

fn spawn_obj(&self, future: FutureObj<'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

fn status(&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.
