Implementations

impl Error

pub fn is_transient(&self) -> bool

Whether this error is transient and the operation should be retried.

pub fn is_swallowable(&self) -> bool

Whether this error should be swallowed (fail-open) by an LLM wrapper.

Transient infrastructure failures (rate limits, network blips, 5xx responses, open circuit breaker, malformed-server-JSON) should not break a chat turn — the model can answer without memory and try again next call. Caller-side errors (auth, validation, config, missing resource) are NOT swallowable — the caller must fix them, retrying won’t help.

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.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

Converts to this type from the input type.
