2026-09-30: Why a checkpoint has no circuit.

Variants

Json

2026-09-30: A file is not the JSON it should be.

Fields

file: &'static str

2026-09-30: config.json or hf_quant_config.json.

detail: String

2026-09-30: What was wrong.

UnknownModelType

2026-09-30: No config map serves this model_type.

Fields

model_type: String

2026-09-30: The config’s model_type.

served: String

2026-09-30: The model types the embedded maps serve.

Map(ConfigMapError)

2026-09-30: The config does not map.

Quant(String)

2026-09-30: The quantization metadata is malformed, or declares a format the circuit has no edge or weight format for.

Precision(PrecisionError)

2026-09-30: A serving-policy name is unknown.

Circuit(CircuitError)

2026-09-30: The circuit does not instantiate under the mapped shape.

Trait Implementations

impl Clone for CheckpointError

fn clone(&self) -> CheckpointError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckpointError

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

Formats the value using the given formatter.

impl Display for CheckpointError

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

Formats the value using the given formatter.

impl Error for CheckpointError

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<CircuitError> for CheckpointError

fn from(source: CircuitError) -> Self

Converts to this type from the input type.

impl From<ConfigMapError> for CheckpointError

fn from(source: ConfigMapError) -> Self

Converts to this type from the input type.

impl From<PrecisionError> for CheckpointError

fn from(source: PrecisionError) -> Self

Converts to this type from the input type.

impl PartialEq for CheckpointError

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