Enum ExternalError

#[non_exhaustive]
pub enum ExternalError {
    NotSupported(NotSupportedError),
    Os(OsError),
}

An error whose cause it outside Tao’s control.

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.

NotSupported(NotSupportedError)

The operation is not supported by the backend.

Os(OsError)

The OS cannot perform the operation.
