Struct BackendError 

pub struct BackendError {
    pub kind: BackendErrorKind,
    pub message: String,
    pub retryable: bool,
}

Error from any backend operation.

This is the universal error type for all backends. It captures the error kind, a human-readable message, and whether the operation can be retried.

Retryable Errors

Some errors are transient (network issues, rate limits) and can be retried. Use is_retryable() to check.

Example

use converge_provider::{BackendError, BackendErrorKind};

let err = BackendError::new(BackendErrorKind::Timeout, "operation timed out");
assert!(err.is_retryable());

let err = BackendError::new(BackendErrorKind::InvalidRequest, "missing field");
assert!(!err.is_retryable());

Fields

kind: BackendErrorKind

Error category.

message: String

Human-readable description.

retryable: bool

Whether this operation can be retried.

Implementations

impl BackendError

pub fn new(kind: BackendErrorKind, message: impl Into<String>) -> Self

Creates a new backend error with automatic retryable detection.

pub fn with_retryable( kind: BackendErrorKind, message: impl Into<String>, retryable: bool, ) -> Self

Creates a new backend error with explicit retryable flag.

pub fn is_retryable(&self) -> bool

Whether this error can be retried.

pub fn auth(message: impl Into<String>) -> Self

Authentication or authorization failure.

pub fn rate_limit(message: impl Into<String>) -> Self

Rate limit or quota exceeded.

pub fn invalid_request(message: impl Into<String>) -> Self

Invalid request parameters.

pub fn unavailable(message: impl Into<String>) -> Self

Backend not available.

pub fn network(message: impl Into<String>) -> Self

Network or connection error.

pub fn backend(message: impl Into<String>) -> Self

Backend returned an error.

pub fn parse(message: impl Into<String>) -> Self

Response could not be parsed.

pub fn timeout(message: impl Into<String>) -> Self

Operation timed out.

pub fn unsupported(capability: &Capability) -> Self

Capability not supported.

pub fn resource_exhausted(message: impl Into<String>) -> Self

Resource exhausted (budget, memory, etc.).

Trait Implementations

impl Clone for BackendError

fn clone(&self) -> BackendError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BackendError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for BackendError

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

Formats the value using the given formatter.

impl Error for BackendError

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 PartialEq for BackendError

fn eq(&self, other: &BackendError) -> 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.

impl Serialize for BackendError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
