Enum PersistenceError 

pub enum PersistenceError {
    NotConfigured,
    BackendShutdown,
    Backend(String),
    Serialization(String),
}

Errors that can occur during persistence operations.

Variants

NotConfigured

The persistence backend is not configured. Returned when calling .query_latest() / .query_range() on an AimDb that was built without .with_persistence().

BackendShutdown

The backend writer thread has shut down (all senders dropped).

Backend(String)

A backend-specific error (e.g. SQLite, Postgres).

Serialization(String)

JSON serialization/deserialization error.

Trait Implementations

impl Debug for PersistenceError

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

Formats the value using the given formatter.

impl Display for PersistenceError

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

Formats the value using the given formatter.

impl Error for PersistenceError

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<Error> for PersistenceError

fn from(e: Error) -> Self

Converts to this type from the input type.
