Enum EngineError 

pub enum EngineError {
    Invalid {
        code: ErrorCode,
        message: String,
        question_id: Option<String>,
    },
    NoLabelMatched {

}

Variants

Invalid

Fields

code: ErrorCode

message: String

question_id: Option<String>

NoLabelMatched

The model answered, but with nothing resembling one of the labels we offered.

Distinct from a host failure: the runtime worked, the model simply did not follow the instruction. Almost always this means the model is too small or too chatty for the job, which is what the benchmark in cerno-bench exists to catch before deployment.

Fields

question_id: String

expected: Vec<String>

observed: Vec<String>

UnknownModel

The host answered 404 to a question naming model.

Every runtime answers a model it does not have that way, and without strict_models that is where a misspelt model surfaces — the caller’s to fix, so not a 5xx inviting a retry. But a host URL missing its /v1 answers 404 to every model as well, so the message says what to check when it is not the model.

Fields

model: String

host: String

source: HostError

Host(HostError)

Implementations

impl EngineError

pub fn code(&self) -> ErrorCode

pub fn question_id(&self) -> Option<&str>

Trait Implementations

impl Debug for EngineError

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

Formats the value using the given formatter.

impl Display for EngineError

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

Formats the value using the given formatter.

impl Error for EngineError

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<HostError> for EngineError

fn from(source: HostError) -> Self

Converts to this type from the input type.
