Struct tokio_executor::SpawnError

pub struct SpawnError { /* fields omitted */ }

[−] Expand description

Errors returned by Executor::spawn.

Spawn errors should represent relatively rare scenarios. Currently, the two scenarios represented by SpawnError are:

• An executor being at capacity or full. As such, the executor is not able to accept a new future. This error state is expected to be transient.
• An executor has been shutdown and can no longer accept new futures. This error state is expected to be permanent.
