Struct MySqlDatabaseError 

pub struct MySqlDatabaseError(/* private fields */);

An error returned from the MySQL database.

Implementations

impl MySqlDatabaseError

pub fn code(&self) -> Option<&str>

The SQLSTATE code for this error.

pub fn number(&self) -> u16

The number for this error.

MySQL tends to use SQLSTATE as a general error category, and the error number as a more granular indication of the error.

pub fn message(&self) -> &str

The human-readable error message.

Trait Implementations

impl DatabaseError for MySqlDatabaseError

fn message(&self) -> &str

The primary, human-readable error message.

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

The (SQLSTATE) code for the error.

fn kind(&self) -> ErrorKind

Returns the kind of the error, if supported.

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 MySqlDatabaseError

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

Formats the value using the given formatter.

impl Display for MySqlDatabaseError

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

Formats the value using the given formatter.

impl Error for MySqlDatabaseError

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
