Enum ErrorCode 

pub enum ErrorCode {
    TooManyOptions,
    TooManyQuestions,
    InvalidRequest,
    TooFewOptions,
    InvalidLevels,
    EmptyState,
    EmptyQuestion,
    DuplicateQuestionId,
    EmptyQuestionId,
    DuplicateOption,
    NoQuestions,
    UnknownModel,

    Internal,
}

Machine-readable failure reasons. Callers branch on these, not on message.

Variants

TooManyOptions

More than MAX_OPTIONS options. v1 does not split these across passes.

TooManyQuestions

More than MAX_QUESTIONS questions in one request.

InvalidRequest

The body is not a request at all: malformed JSON, a wrong type, an unknown field, or a question naming more or fewer than one primitive.

TooFewOptions

Option list empty, or a single option — there is nothing to decide.

InvalidLevels

Level count outside MIN_LEVELS..=MAX_LEVELS.

EmptyState

EmptyQuestion

DuplicateQuestionId

EmptyQuestionId

A question id that is empty or only whitespace. The id is how its answer is found.

DuplicateOption

Two options, or two score levels, with the same text. The model is shown both, and the probability splits between them.

NoQuestions

UnknownModel

InvalidCalibration

NoLabelMatched

The model answered with no recognisable label — it is not following the instruction.

HostUnavailable

HostTimeout

Internal

A failure inside cerno itself. Not the caller’s doing, and not the model’s.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl ComposeSchema for ErrorCode

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Copy for ErrorCode

impl Debug for ErrorCode

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ErrorCode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ErrorCode

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ErrorCode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for ErrorCode

impl ToSchema for ErrorCode

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference [utoipa::openapi::schema::Schema]s for this type.
