Enum GenerateError 

pub enum GenerateError<E> {
    Provider(E),
    Parse {
        source: Error,
        response: String,
    },
}

Why a structured-output call failed.

LanguageModel::respond reports provider failures through the model’s own LanguageModel::Error. Structured output adds a second, separate way to fail — the model answered, but not with the requested shape — so this keeps the two distinguishable instead of flattening both into one opaque error. Callers need that distinction: a rate limit is worth retrying, a schema mismatch is worth re-prompting, and an auth failure is worth neither.

Variants

Provider(E)

The provider itself failed: transport, rate limit, auth, and so on.

Parse

The provider answered, but the response did not match the schema.

Carries the text that could not be parsed so callers can log or retry.

Fields

source: Error

The underlying deserialization failure.

response: String

The response text that failed to parse, truncated for logging.

Trait Implementations

impl<E: Debug> Debug for GenerateError<E>

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

Formats the value using the given formatter.

impl<E: Display> Display for GenerateError<E>

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

Formats the value using the given formatter.

impl<E: Error + 'static> Error for GenerateError<E>

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>)
