Retryable inference error (network issues, rate limits, 5xx errors)

ContextLengthExceeded(String)

Context length exceeded (prompt + completion too long)

RetriesExceeded(String)

Maximum retries exhausted (includes last error for context)

NonRetryable(String)

Non-retryable error (validation, 4xx errors)

Parse(String)

Parse error when parsing LLM output

Validation(String)

Validation error for structured outputs

ToolNotFound(String)

Tool not found in registry

Network(Error)

Network error from reqwest

Json(Error)

JSON serialization/deserialization error

Utf8(Utf8Error)

UTF-8 encoding error

FromUtf8(FromUtf8Error)

UTF-8 conversion error from String

Io(Error)

IO error

InvalidProvider(String)

Invalid provider specified

MissingApiKey(String)

Missing API key

RuntimeNotUsed

Runtime not used (validation error)

Implementations

impl Error

pub fn is_retryable(&self) -> bool

Check if error is retryable (suitable for backoff retry)

pub fn is_retries_exceeded(&self) -> bool

Check if error indicates retries were exceeded

pub fn is_incomplete(&self) -> bool

Check if error indicates incomplete/partial data (for streaming)

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
