Struct ExaDatabaseError

pub struct ExaDatabaseError { /* private fields */ }

An error directly issued by the Exasol database. Implementor of DatabaseError.

Trait Implementations

impl DatabaseError for ExaDatabaseError

fn kind(&self) -> ErrorKind

Uniqueness is only available to PRIMARY KEY columns in Exasol. Additionally, there’s no distinction between the PRIMARY and FOREIGN key constraint violation codes, so we have to rely on the message as well.

Furthermore, there’s no CHECK constraint in Exasol.

fn message(&self) -> &str

The primary, human-readable error message.

fn code(&self) -> Option<Cow<'_, str>>

The (SQLSTATE) code for the error.

fn constraint(&self) -> Option<&str>

Returns the name of the constraint that triggered the error, if applicable. If the error was caused by a conflict of a unique index, this will be the index name.

fn table(&self) -> Option<&str>

Returns the name of the table that was affected by the error, if applicable.

fn is_unique_violation(&self) -> bool

Returns whether the error kind is a violation of a unique/primary key constraint.

fn is_foreign_key_violation(&self) -> bool

Returns whether the error kind is a violation of a foreign key.

fn is_check_violation(&self) -> bool

Returns whether the error kind is a violation of a check.

impl Debug for ExaDatabaseError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ExaDatabaseError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ExaDatabaseError

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

Formats the value using the given formatter.

impl Error for ExaDatabaseError

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.
