Enum DriverError 

#[non_exhaustive]
pub enum DriverError<RegistryError, ExecutorError> {
    Registry(RegistryError),
    Executor(ExecutorError),
}

Error returned by a driver step.

#[non_exhaustive]: an error enumeration grows as new failure modes appear, so a downstream match must carry a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Registry(RegistryError)

Registry operation failed.

Executor(ExecutorError)

Executor infrastructure failed; the claim was left unsettled to lapse and be reclaimed (no settlement was recorded).

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
