Enum Error 

#[non_exhaustive]
pub enum Error {
    DeSerialization(DeSerError),
    Poison,
    Backend(BackendError),
    WritePanic,
}

The different kinds of errors that can be returned

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.

DeSerialization(DeSerError)

A context error when a DeSerialization failed

Poison

This error is returned if the Database is poisoned. See Database::write for details

Backend(BackendError)

An error in the backend happened

WritePanic

If Database::write_safe is used and the closure panics, this error is returned

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

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

impl From<BackendError> for Error

fn from(source: BackendError) -> Self

Converts to this type from the input type.

impl From<DeSerError> for Error

fn from(source: DeSerError) -> Self

Converts to this type from the input type.
