Enum StoreError 

pub enum StoreError {
    Io(Error),
    Serialization(Error),
    Sqlite(Error),
    NotFound(SessionId),
    Corrupted(SessionId),
    Join(JoinError),
    Internal(String),
    RealmManifestLockTimeout {
        realm_id: String,
    },
    RealmBackendMismatch {
        realm_id: String,
        requested: String,
        existing: String,
    },
    UnsupportedRealmBackend {
        realm_id: String,
        backend: String,
    },
    RealmIdentityMismatch {
        requested: String,
        existing: String,
    },
    InvalidRealmSlug(String),
}

Backend-specific error type used internally by meerkat-store implementations.

External consumers should use SessionStoreError (from meerkat-core) for the SessionStore trait boundary. This type carries backend-specific variants (for example rusqlite) that the trait contract intentionally erases.

Variants

Io(Error)

Serialization(Error)

Sqlite(Error)

NotFound(SessionId)

Corrupted(SessionId)

Join(JoinError)

Internal(String)

RealmManifestLockTimeout

Fields

realm_id: String

RealmBackendMismatch

Fields

realm_id: String

requested: String

existing: String

UnsupportedRealmBackend

Fields

realm_id: String

backend: String

RealmIdentityMismatch

The requested realm id sanitizes to the same on-disk path as an existing manifest that pins a different realm identity (e.g. the raw slugs a.b and a_b both sanitize to the a_b directory). Two distinct realm identities must never silently share one manifest, so the path-aliased open is rejected fail-closed rather than handing back the wrong realm’s manifest.

Fields

requested: String

existing: String

InvalidRealmSlug(String)

Persisted manifest carried a realm id that fails the typed slug validator (wave-c C-12 sibling retype — the on-disk form is free-string but the domain type is RealmId which enforces the slug grammar). Reported when an on-disk manifest was hand-edited to an unparseable realm slug.

Implementations

impl StoreError

pub fn into_session_store_error(self) -> SessionStoreError

Convert to the backend-agnostic SessionStoreError at the trait boundary.

Trait Implementations

impl Debug for StoreError

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

Formats the value using the given formatter.

impl Display for StoreError

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

Formats the value using the given formatter.

impl Error for StoreError

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
