Implementations

impl AppError

pub fn from_lock_poison<T>(resource: &str, _err: PoisonError<T>) -> Self

Create a lock poisoned error from a PoisonError

pub fn lock_failed(resource: &str, reason: &str) -> Self

Create a lock acquisition failure

pub fn code(&self) -> &'static str

Get error code for client identification

pub fn status_code(&self) -> StatusCode

Get HTTP status code

pub fn message(&self) -> String

Get detailed error message

pub fn to_response(&self) -> ErrorResponse

Convert to structured error response

pub fn to_response_with_request_id( &self, request_id: Option<String>, ) -> ErrorResponse

Trait Implementations

impl Debug for AppError

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

Formats the value using the given formatter.

impl Display for AppError

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

Formats the value using the given formatter.

impl Error for AppError

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<Error> for AppError

Convert from anyhow::Error to AppError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl IntoResponse for AppError

Axum IntoResponse implementation for proper HTTP responses

fn into_response(self) -> Response

Create a response.
