Enum BackendError 

pub enum BackendError {
    Generic {
        status_code: i64,
        body: String,
    },
    ThinkingNotSupported {
        model: String,
        status_code: i64,
        body: String,
    },
}

Error indicating that the backend request failed.

Variants

Generic

A generic backend failure with status code and body description.

Fields

status_code: i64

The HTTP or API status code returned by the backend.

body: String

The response body containing error details.

ThinkingNotSupported

Error indicating that thinking mode is not supported by the model.

Fields

model: String

The model name.

status_code: i64

The status code.

body: String

The body.

Implementations

impl BackendError

pub fn new(status_code: i64, body: impl Into<String>) -> Self

Creates a new generic BackendError.

pub fn status_code(&self) -> i64

Returns the HTTP/API status code carried by this error (0 for a transport-level failure where no HTTP response was received).

pub fn status_from_display(message: &str) -> Option<i64>

Recovers the status code from a BackendError::Generic Display string (Backend error (status N): ...).

This is for boundaries where an upstream error has already been flattened to text (for example a stream-start failure surfaced as a StreamError). Typed call sites use BackendError::status_code instead, so this parser is never applied to arbitrary wrapped messages.

pub fn thinking_not_supported(model: impl Into<String>) -> Self

Creates a ThinkingNotSupported backend error.

Trait Implementations

impl Debug for BackendError

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

Formats the value using the given formatter.

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 From<BackendError> for ForgeError

fn from(source: BackendError) -> Self

Converts to this type from the input type.
