Enum DbError 

pub enum DbError {
    Io(Error),
    Format(FormatError),
    Schema(SchemaError),
    Validation(ValidationError),
    Transaction(TransactionError),
    Query(QueryError),
    NotImplemented,
}

Variants

Io(Error)

Failed to access the database file or path.

Format(FormatError)

Failed to parse or validate the on-disk format (header, superblock, segments, payloads).

Schema(SchemaError)

Catalog or row did not satisfy schema invariants.

Validation(ValidationError)

Row value failed type or constraint checks before persistence.

Transaction(TransactionError)

Transaction nesting or API misuse (0.8+).

Query(QueryError)

Query construction, parsing, or execution error (SQL adapter and query planner).

NotImplemented

Requested capability is not implemented in this release (e.g. nested field paths in rows).

Implementations

impl DbError

pub fn kind(&self) -> DbErrorKind

pub fn details(&self) -> BTreeMap<String, String>

Machine-readable key/value pairs for the specific error variant (empty for I/O).

Trait Implementations

impl Debug for DbError

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

Formats the value using the given formatter.

impl Display for DbError

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

Formats the value using the given formatter.

impl Error for DbError

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<CatalogDecodeError> for DbError

fn from(e: CatalogDecodeError) -> DbError

Converts to this type from the input type.

impl From<Error> for DbError

fn from(value: Error) -> DbError

Converts to this type from the input type.
