}

Event cache store specific error type.

Variants

Backend(Box<dyn Error + Send + Sync>)

An error happened in the underlying database backend.

Locked

The store is locked with a passphrase and an incorrect passphrase was given.

Unencrypted

An unencrypted store was tried to be unlocked with a passphrase.

Encryption(StoreEncryptionError)

The store failed to encrypt or decrypt some data.

Codec(Utf8Error)

The store failed to encode or decode some data.

Serialization(Error)

The store failed to serialize or deserialize some data.

UnsupportedDatabaseVersion(usize, usize)

The database format has changed in a backwards incompatible way.

InvalidData

The store contains invalid data.

Fields

details: String

Details why the data contained in the store was invalid.

Implementations

impl EventCacheStoreError

pub fn backend<E>(error: E) -> Self

where E: Error + Send + Sync + 'static,

Create a new Backend error.

Shorthand for EventCacheStoreError::Backend(Box::new(error)).

Trait Implementations

impl Debug for EventCacheStoreError

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

Formats the value using the given formatter.

impl Display for EventCacheStoreError

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

Formats the value using the given formatter.

impl Error for EventCacheStoreError

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.
