Enum SqliteError 

pub enum SqliteError {
    Rusqlite(Error),
    Pool(String),
    LockPoisoned,
    Migration(String),
    SchemaTooNew {
        found: i64,
        supported: i64,
    },
    Backup(String),
}

Errors from the SQLite storage layer.

Variants

Rusqlite(Error)

Pool(String)

LockPoisoned

👎Deprecated:

No longer emitted after the r2d2 pool migration. Match SqliteError::Pool instead. Kept so older downstream match arms still compile.

Retained for back-compat with downstream match arms. New code should emit SqliteError::Pool for connection-acquisition failures; with the r2d2 pool we no longer hold a Mutex that can poison. Treat any inbound LockPoisoned as equivalent to Pool for routing decisions.

Migration(String)

SchemaTooNew

The on-disk schema is newer than this binary knows how to run. Forward-only migrations can’t walk a schema backwards, so opening would mean operating an old binary on a future schema — the data-corruption path. Refused unless the caller opts into a downgrade override.

Fields

found: i64

supported: i64

Backup(String)

A pre-migration snapshot of the database could not be written. Treated as fatal: we will not mutate an existing schema without a recoverable copy in hand.

Trait Implementations

impl Debug for SqliteError

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

Formats the value using the given formatter.

impl Display for SqliteError

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

Formats the value using the given formatter.

impl Error for SqliteError

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.
