Struct ProviderError 

pub struct ProviderError {
    pub operation: String,
    pub message: String,
    pub retryable: bool,
}

Provider-specific error with retry classification

Providers return this error type to indicate whether an error should be retried. The runtime uses is_retryable() to decide whether to retry the operation.

Error Classification

Retryable (is_retryable = true):

• Database busy/locked
• Connection timeouts
• Network failures
• Temporary resource exhaustion

Non-retryable (is_retryable = false):

• Data corruption (missing instance, invalid format)
• Duplicate events (indicates bug)
• Invalid input (malformed work item)
• Configuration errors
• Invalid lock tokens (idempotent - already processed)

Example Usage

use duroxide::providers::ProviderError;

// Transient error - retryable
return Err(ProviderError::retryable("ack_orchestration_item", "Database is busy"));

// Permanent error - not retryable
return Err(ProviderError::permanent("ack_orchestration_item", "Duplicate event detected"));

Fields

operation: String

Operation that failed (e.g., “ack_orchestration_item”, “fetch_orchestration_item”)

message: String

Human-readable error message

retryable: bool

Whether this error should be retried

Implementations

impl ProviderError

pub fn retryable( operation: impl Into<String>, message: impl Into<String>, ) -> Self

Create a retryable (transient) error

Use for errors that might succeed on retry:

• Database busy/locked
• Connection timeouts
• Network failures

pub fn permanent( operation: impl Into<String>, message: impl Into<String>, ) -> Self

Create a non-retryable (permanent) error

Use for errors that won’t succeed on retry:

• Data corruption
• Duplicate events
• Invalid input
• Configuration errors
• Invalid lock tokens (idempotent)

pub fn is_retryable(&self) -> bool

Check if error is retryable

pub fn to_infrastructure_error(&self) -> ErrorDetails

Convert to ErrorDetails::Infrastructure for runtime

Trait Implementations

impl Clone for ProviderError

fn clone(&self) -> ProviderError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProviderError

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

Formats the value using the given formatter.

impl Display for ProviderError

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

Formats the value using the given formatter.

impl Error for ProviderError

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<&str> for ProviderError

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<ProviderError> for ClientError

fn from(e: ProviderError) -> Self

Converts to this type from the input type.

impl From<String> for ProviderError

Conversion from String for backward compatibility

fn from(s: String) -> Self

Convert String error to retryable ProviderError

This allows existing code that returns Err(String) to work. By default, String errors are treated as retryable (conservative approach).

impl PartialEq for ProviderError

fn eq(&self, other: &ProviderError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
