Enum SqlError 

#[non_exhaustive]
pub enum SqlError {
    Backend(Redacted),
    Constraint,
    Full,
    Corrupt(&'static str),
}

Why a SQL call failed. The backend’s own message never reaches a client: it is kept Redacted for the server-side log only.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Backend(Redacted)

The engine failed (I/O, busy past its timeout, a malformed statement). The outcome of a failed transaction is a rollback.

Constraint

A constraint was violated.

Full

The database is at its size cap (SQLITE_FULL): writes that add data fail, reads and deletes keep working.

Corrupt(&'static str)

A row did not have the expected shape.

Trait Implementations

impl Debug for SqlError

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

Formats the value using the given formatter.

impl Display for SqlError

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

Formats the value using the given formatter.

impl Error for SqlError

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<SqlError> for StoreError

fn from(e: SqlError) -> Self

Converts to this type from the input type.
