Trait Implementations

impl Debug for DriverError

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

Formats the value using the given formatter.

impl Display for DriverError

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

Formats the value using the given formatter.

impl Error for DriverError

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<DriverError> for Error

fn from(err: DriverError) -> Self

Converts to this type from the input type.

impl From<LocalInfileError> for DriverError

fn from(source: LocalInfileError) -> Self

Converts to this type from the input type.

impl From<MissingNamedParameterError> for DriverError

fn from(err: MissingNamedParameterError) -> Self

Converts to this type from the input type.

impl From<MixedParamsError> for DriverError

fn from(_err: MixedParamsError) -> Self

Converts to this type from the input type.
