# Trait futures_task::Spawn [−] [src]

    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>` [src]

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>` [src]

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.
