Enum FittedModelError 

pub enum FittedModelError {
    SchemaMismatch {
        reason: String,
    },
    PayloadCorrupt {
        reason: String,
    },
    MissingField {
        reason: String,
    },
    IncompatibleConfig {
        reason: String,
    },
    InvalidInput {
        reason: String,
    },
}

Typed error surface for src/inference/model.rs saved-model code.

Every variant carries a free-form reason: String payload; Display emits exactly that payload, so converting a FittedModelError into String (via the From impl below) is byte-equivalent to the pre- refactor Err(format!(...)) / Err("...".to_string()) strings that the same call sites produced. This lets external callers keep using ? against Result<_, String> without source changes — the typed enum is purely an in-module discipline gain.

Variants

SchemaMismatch

Saved payload structure / shape / version disagrees with what the current binary expects (e.g. covariance shape, block ordering, schema version, C2 continuity, out-of-range span/basis indices).

Fields

reason: String

PayloadCorrupt

Saved payload bytes / numeric content are corrupt or unreadable (non-finite scalars, invalid JSON, IO failure, malformed stateful link state).

Fields

reason: String

MissingField

A required field that the current code path needs is absent from the payload (typically ..; refit errors).

Fields

reason: String

IncompatibleConfig

A combination of saved-model options is not supported by the current binary (unsupported deployment-extension kind, unsupported kernel marker, unsupported survival_time_basis variant, etc.).

Fields

reason: String

InvalidInput

An input value rejected by a save-time sanity gate (e.g. negative ridge alpha).

Fields

reason: String

Trait Implementations

impl Clone for FittedModelError

fn clone(&self) -> FittedModelError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FittedModelError

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

Formats the value using the given formatter.

impl Display for FittedModelError

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

Formats the value using the given formatter.

impl Eq for FittedModelError

impl Error for FittedModelError

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<FittedModelError> for String

fn from(err: FittedModelError) -> String

Converts to this type from the input type.

impl From<FittedModelError> for EstimationError

fn from(err: FittedModelError) -> Self

Converts to this type from the input type.

impl From<FittedModelError> for SurvivalPredictError

fn from(err: FittedModelError) -> Self

Converts to this type from the input type.

impl PartialEq for FittedModelError

fn eq(&self, other: &FittedModelError) -> 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.
