Implementations

impl Error

pub const fn category(&self) -> ErrorCategory

Categorize error for retry logic

pub const fn is_retryable(&self) -> bool

Check if error is retryable

pub const fn retry_after(&self) -> Option<Duration>

Get suggested retry delay for rate limited errors

pub const fn should_trigger_circuit_breaker(&self) -> bool

Check if error indicates a need for circuit breaker

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
