Struct BoxError 

pub struct BoxError(/* private fields */);

A provider error erased to one concrete type, so backends with differing associated Errors can be stored behind a single trait object.

Transparent wrapper: Display delegates to the inner error and source exposes it, so logs and error chains read exactly as the un-erased error did. The second field preserves the original LlmErrorKind across erasure (the boxed dyn Error alone could not be re-classified).

Implementations

impl BoxError

pub fn new<E: LlmError>(err: E) -> Self

Erase any LlmError into a BoxError, capturing its kind so the classification survives erasure.

Trait Implementations

impl Debug for BoxError

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

Formats the value using the given formatter.

impl Display for BoxError

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

Formats the value using the given formatter.

impl Error for BoxError

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 LlmError for BoxError

fn kind(&self) -> LlmErrorKind

Classify this error so a transport (e.g. the harness’s Connect surface) can map it onto an accurate status code — telling retryable (rate-limit / timeout / unavailable) apart from terminal (auth / bad-request) failures instead of collapsing everything to a catch-all.
