Struct ClassifiedError 

pub struct ClassifiedError {
    pub class: Class,
    pub source: Box<dyn Error + Send + Sync + 'static>,
    /* private fields */
}

An error with its class, from any crate: the one error type a venue-neutral caller handles.

Built from any Classify error with ? or .into(), which records the class, is_fault and retry_after as the error reported them. It displays as its source does and continues the source chain from there, so wrapping an error changes nothing an error reporter prints. The original error stays reachable through source, by downcasting.

It does not implement Classify itself: that would make the blanket From overlap From<T> for T. Read the class from the class field.

Fields

class: Class

The error’s class.

source: Box<dyn Error + Send + Sync + 'static>

The error that was classified.

Implementations

impl ClassifiedError

pub fn new( class: Class, source: impl Into<Box<dyn Error + Send + Sync + 'static>>, ) -> Self

Classifies an error that does not implement Classify. It counts as a fault, and its wait is its class’s.

pub fn is_fault(&self) -> bool

Whether the error is a fault, as Classify::is_fault reported it.

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

The wait the server asked for, as Classify::retry_after reported it.

pub fn is_retriable(&self) -> bool

Whether retrying could plausibly succeed (see Class::is_retriable).

Trait Implementations

impl Debug for ClassifiedError

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

Formats the value using the given formatter.

impl Display for ClassifiedError

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

Formats the value using the given formatter.

impl Error for ClassifiedError

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<E> From<E> for ClassifiedError

where E: Classify + Send + Sync + 'static,

fn from(err: E) -> Self

Converts to this type from the input type.
