Enum ProcessingError 

pub enum ProcessingError {
    Retryable {
        message: String,
        custom_delay: Option<Duration>,
    },
    NonRetryable {
        message: String,
        send_to_dlq: bool,
    },
}

Processing error types for consumer handlers

Variants

Retryable

Retryable error - message should be retried with delay

Fields

message: String

custom_delay: Option<Duration>

Optional custom retry delay override

NonRetryable

Non-retryable error - message should be rejected permanently

Fields

message: String

send_to_dlq: bool

Whether to send to dead letter queue (default: true)

Implementations

impl ProcessingError

pub fn retryable<S: Into<String>>(message: S) -> Self

Create a retryable error with default delay

pub fn retryable_with_delay<S: Into<String>>( message: S, delay: Duration, ) -> Self

Create a retryable error with custom delay

pub fn non_retryable<S: Into<String>>(message: S) -> Self

Create a non-retryable error (will be sent to DLQ)

pub fn discard<S: Into<String>>(message: S) -> Self

Create a non-retryable error that should be discarded (not sent to DLQ)

pub fn is_retryable(&self) -> bool

Check if this error is retryable

pub fn should_send_to_dlq(&self) -> bool

Check if this error should be sent to DLQ

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

Get custom delay if specified

Trait Implementations

impl Clone for ProcessingError

fn clone(&self) -> ProcessingError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProcessingError

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

Formats the value using the given formatter.

impl Display for ProcessingError

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

Formats the value using the given formatter.

impl Error for ProcessingError

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.
