Trait Implementations

impl Clone for DriverError

fn clone(&self) -> DriverError

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

pub fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<DriverError> for Error

fn from(err: DriverError) -> Self

Performs the conversion.

impl From<MissingNamedParameterError> for DriverError

fn from(err: MissingNamedParameterError) -> Self

Performs the conversion.

impl From<MixedParamsError> for DriverError

fn from(_err: MixedParamsError) -> Self

Performs the conversion.

impl PartialEq<DriverError> for DriverError

fn eq(&self, other: &DriverError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &DriverError) -> bool

This method tests for !=.
