impl<E> Display for PersistError<E>

where E: Display + Error,

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

impl<E: Error> Error for PersistError<E>

where Self: Debug + Display,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl<E: Error> From<ExportError> for PersistError<E>

fn from(source: ExportError) -> Self
