Implementations

impl AppError

pub fn code(&self) -> ErrorCode

Get the error code for this error type.

pub fn is_retryable(&self) -> bool

Check if this error is transient and retrying with a fallback provider may succeed (timeout, rate limit, 5xx upstream).

pub fn status_code(&self) -> u16

HTTP status code as u16 (no axum dependency).

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, __formatter: &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

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for AppError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<QuotaExceeded> for AppError

fn from(exceeded: QuotaExceeded) -> Self

Converts to this type from the input type.
