Struct TxConflictError 

pub struct TxConflictError { /* private fields */ }

The error a backend reports for a TxConflict, carrying the engine’s own code and message and (usually) the driver error as its source.

Backend-facing: construct one, then TxConflictError::into_exec_error.

Implementations

impl TxConflictError

pub fn new( kind: TxConflict, code: impl Into<String>, message: impl Into<String>, ) -> Self

A conflict of kind, as the engine reported it (code is the engine’s own: a SQLSTATE, an error number, a SQLite result code).

pub fn with_source(self, e: impl Error + Send + Sync + 'static) -> Self

Keep the driver error underneath, so nothing is lost by classifying.

pub fn kind(&self) -> TxConflict

Which conflict this is.

pub fn code(&self) -> &str

The engine’s own code.

pub fn into_exec_error(self) -> ExecError

Wrap into the error the executor traits speak. This is the one construction TxConflict::of recognises.

Trait Implementations

impl Debug for TxConflictError

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

Formats the value using the given formatter.

impl Display for TxConflictError

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

Formats the value using the given formatter.

impl Error for TxConflictError

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.
