LLM error types.

Comprehensive error types covering all failure modes when interacting with LLM providers.

Variants

AuthError(String)

Authentication failed with the provider.

This typically indicates an invalid API key or expired credentials.

RateLimited

Rate limited by the provider.

The provider is limiting request rate. The caller should wait for the specified duration before retrying.

Fields

retry_after: Option<Duration>

Suggested wait duration before retrying.

ContextLengthExceeded

Context length exceeded.

The input message count or token count exceeds the model’s context window.

Fields

used: u64

Actual token count used.

limit: u64

Maximum context window size.

NetworkError(String)

Generic network error.

Used when no provider features are enabled.

InvalidResponse(String)

Invalid response from provider.

The provider returned a response that could not be parsed or was malformed.

ModelNotFound(String)

Model not found.

The requested model name does not exist or is not available.

ContentFiltered

Content filtered by provider.

The provider refused to process the content due to policy violations.

Timeout(Duration)

Request timeout.

The provider did not respond within the specified time limit.

Other(Box<dyn Error + Send + Sync>)

Other error.

Catch-all for errors not covered by specific variants.

Trait Implementations

impl Debug for LlmError

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

Formats the value using the given formatter.

impl Display for LlmError

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

Formats the value using the given formatter.

impl Error for LlmError

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.
