Stable since 0.63.0

Provider-specific error type for LLM operations. Provider-specific errors. `#[non_exhaustive]` — consumers MUST add a catch-all `_ =>` arm in their `match` expressions. Existing named variants are frozen; their meaning does not change between releases (see `docs/release-process.md`).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

MissingApiKey

API key is missing.

UnknownProvider(String)

Unknown provider.

NotImplemented(String)

Provider not yet implemented.

HttpError(HttpErrorDetail)

HTTP error with structured detail (status, body, provider, request-id).

RequestFailed(Error)

HTTP request failed.

IoError(Error)

I/O error.

InvalidResponse(String)

Invalid response from provider.

InvalidApiKey

Invalid API key format.

JsonParse(Error)

JSON parsing error.

StreamError(String)

Streaming error.

NetworkError(String)

Network error.

ContextOverflow

Context window overflow.

Timeout

Request timed out.

RateLimited

Rate limit exceeded.

Fields

retry_after: Option<Duration>

Wait time suggested by the server.

Implementations

impl ProviderError

pub fn is_retryable(&self) -> bool

Returns whether this error is retryable.

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

Returns the retry wait time suggested by the server.

pub fn http_status(&self) -> Option<u16>

Returns the HTTP status code if this is an HTTP error, else None.

Convenience for call sites that previously destructured the old HttpError(u16, String) tuple (e.g. inside matches!, which cannot carry a guard).

Trait Implementations

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, __formatter: &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.
