Implementations

impl LlmError

pub fn timeout(duration: Duration) -> Self

Create a timeout error from a Duration

pub fn is_retryable(&self) -> bool

Whether this error is retryable

pub fn is_auth(&self) -> bool

Whether this error is an authentication error

pub fn is_rate_limited(&self) -> bool

Whether this error was rate-limited

pub fn retry_after_secs(&self) -> Option<u64>

Get retry-after hint if available

pub fn truncated_message(&self, max_len: usize) -> String

Truncate error message to a maximum length (for logging safety)

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.

impl From<Error> for LlmError

Available on crate feature openai only.

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for LlmError

fn from(err: Error) -> Self
