Variants

InvalidIdentifier

Fields

value: String

reason: &'static str

Validation(String)

FingerprintMismatch

A recomputed or declared fingerprint did not match the expected value (schema, plan, relation or params) — a replay/compatibility failure that a host can route differently from a plain validation error.

Fields

kind: &'static str

expected: String

actual: String

UnknownHandle

A data or view handle was released or never issued; the caller is using a stale or unknown handle against the coordinator arena.

Fields

kind: &'static str

handle: u64

RelationBoundaryViolation

A supplied fold set leaks a repetition group or augmentation origin across the train/validation boundary (the ADR-05 safety invariant).

Fields

kind: &'static str

detail: String

IncompatibleReducer

An aggregation reducer is incompatible with the prediction task it was applied to (for example vote on a regression task) — ADR-07.

Fields

reducer: &'static str

task: &'static str

SignalTypeMismatch

A provider-declared signal type does not match the one the plan or bundle expects (for example an absorbance-trained pipeline applied to raw reflectance) — ADR-06.

Fields

expected: &'static str

actual: &'static str

Serialization(Error)

Implementations

impl DataError

pub fn category(&self) -> &'static str

Return the stable ADR-11 category for this error.

pub fn code(&self) -> &'static str

Return the stable ADR-11 code for this error.

pub fn severity(&self) -> &'static str

Return the ADR-11 severity for this error.

pub fn remediation_hint(&self) -> &'static str

Return the remediation hint associated with this error.

pub fn context(&self) -> BTreeMap<String, Value>

Return structured context fields for logs, bindings and tests.

pub fn descriptor(&self) -> DataErrorDescriptor

Build the serializable ADR-11 descriptor for this error.

pub fn descriptor_json(&self) -> Result<String, Error>

Serialize the ADR-11 descriptor as compact JSON.

pub fn error_code(&self) -> u32

Stable ADR-11 numeric error code for FFI consumers: the high 16 bits are the taxonomy category id and the low 16 bits are the per-category code id, mirroring the (category << 16) | code convention from ADR-11. The category ids are shared with dag-ml so a given category maps to the same number in both libraries.

Trait Implementations

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Error for DataError

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 DataError

fn from(source: Error) -> Self

Converts to this type from the input type.
