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

An error returned from the MySQL database.

Implementations§

source§

impl MySqlDatabaseError

source

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

The SQLSTATE code for this error.

source

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.

source

pub fn message(&self) -> &str

The human-readable error message.

Trait Implementations§

impl DatabaseError for MySqlDatabaseError

source§

fn message(&self) -> &str

The primary, human-readable error message.
source§

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

The (SQLSTATE) code for the error.
source§

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. Read more
