Database operation errors

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.

UnsupportedFeature

Feature not supported by this database

Fields

database: String

The database that does not support the feature.

feature: String

The feature that is not supported.

NotSupported(String)

Operation not supported by this backend

SyntaxError(String)

SQL syntax error

TypeError(String)

Type conversion error

ConnectionError(String)

Connection error

QueryError(String)

Query execution error

SerializationError(String)

Serialization/deserialization error

ConfigError(String)

Configuration error

ColumnNotFound(String)

Column not found error

TransactionError(String)

Transaction error

Other(String)

Generic database error

Trait Implementations

impl Clone for DatabaseError

fn clone(&self) -> DatabaseError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DatabaseError

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

Formats the value using the given formatter.

impl Display for DatabaseError

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

Formats the value using the given formatter.

impl Error for DatabaseError

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<DatabaseError> for ExecutionError

fn from(source: DatabaseError) -> ExecutionError

Converts to this type from the input type.

impl From<DatabaseError> for MigrationError

fn from(source: DatabaseError) -> MigrationError

Converts to this type from the input type.

impl From<Error> for DatabaseError

fn from(err: Error) -> DatabaseError

Converts to this type from the input type.

impl From<Error> for DatabaseError

fn from(err: Error) -> DatabaseError

Converts to this type from the input type.

impl PartialEq for DatabaseError

fn eq(&self, other: &DatabaseError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
