Pager error types

Variants

Io(Error)

I/O error

Page(PageError)

Page error

InvalidDatabase(String)

Invalid database file

ReadOnly

Database is read-only

PageNotFound(u32)

Page not found

Locked

Database is locked

LockPoisoned

A Mutex or RwLock was poisoned (another thread panicked while holding it)

EncryptionRequired

Database is encrypted but no key was supplied.

PlainDatabaseRefusesKey

Plain (unencrypted) database opened with an encryption key.

InvalidKey

Encryption key validation failed for an encrypted database.

SuperblockZoneUnrecoverable(PathBuf)

Both superblock copies failed validation (ADR 0074 §2).

ManifestZoneCorrupt(PathBuf)

The internal manifest zone failed its checksum (ADR 0074 §2).

DwbZoneCorrupt(PathBuf)

The in-file double-write zone failed validation (ADR 0074 §2).

LegacySidecarStore

The store still carries a retired phase-1 pager sidecar (ADR 0038 §4).

Fields

sidecar: PathBuf

LegacyPagedStore

The store predates the phase-3 in-file DWB layout marker (ADR 0038 §4).

Fields

path: PathBuf

Trait Implementations

impl Debug for PagerError

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

Formats the value using the given formatter.

impl Display for PagerError

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

Formats the value using the given formatter.

impl Error for PagerError

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.
