Enum BridgeError 

pub enum BridgeError {
    WorkerDead,
    ResponseLost,
}

Errors returned by RuntimeBridge::block_on when the bridge cannot complete a request. Both variants signal an unrecoverable problem with the worker for this one call; the bridge as a whole remains usable for subsequent calls only when BridgeError::ResponseLost is returned (the worker is still alive, just this one task died).

Variants

WorkerDead

The worker thread is gone — sending the task failed because the receiver side of the dispatch channel was dropped. In practice this means the worker thread panicked while building or driving its runtime; every later call will return the same error.

ResponseLost

The task was accepted but no reply ever arrived. The future panicked mid-poll (so its reply sender was dropped without sending) or the worker’s runtime was shut down underneath an in-flight task. Other in-flight requests on the same bridge are unaffected.

Trait Implementations

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
