Trait Implementations

impl DatabaseError for ScyllaDBError

fn message(&self) -> &str

The primary, human-readable error message.

fn kind(&self) -> ErrorKind

Returns the kind of the error, if supported.

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 ScyllaDBError

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

Formats the value using the given formatter.

impl Display for ScyllaDBError

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

Formats the value using the given formatter.

impl Error for ScyllaDBError

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.
