Variants

Internal(String)

An internal error occurred

NotSupported(String)

An operation was requested that is not supported

InvalidShape(String)

An invalid tensor shape was given

Yaml(Error)

An error occurred while parsing YAML

Json(Error)

An error occurred while parsing YAML

NoConfig

Attmpted to use build a decoder without configuration

InvalidConfig(String)

The provide decoder configuration was invalid

NDArrayShape(ShapeError)

An error occurred with ndarray shape operations

DtypeMismatch

Schema-declared per-scale child dtype != bound tensor dtype at run time.

Fields

expected: DType

actual: DType

role: &'static str

level: usize

QuantMissing

Integer tensor bound to a role that requires dequantization, but the tensor carries no Quantization metadata. The upstream inference layer must call tensor.set_quantization(...) before invoking the decoder, or callers may use per_scale::apply_schema_quant() as a fallback.

Fields

dtype: DType

role: &'static str

level: usize

KernelDispatchUnreachable(String)

Internal logic bug — a dispatch variant was constructed but the concrete kernel wasn’t matched. Indicates a missing arm in the dispatch enum’s run() impl.

ForcedKernelUnavailable

EDGEFIRST_DECODER_FORCE_KERNEL requested a tier whose features the running CPU doesn’t support.

Fields

tier: &'static str

missing_feature: &'static str

Trait Implementations

impl Debug for DecoderError

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

Formats the value using the given formatter.

impl Display for DecoderError

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

Formats the error for display

Arguments

• f - The formatter to write to

Returns

A result indicating success or failure

Examples

use edgefirst_decoder::DecoderError;
let err = DecoderError::InvalidConfig("The config was invalid".to_string());
println!("{}", err);

impl Error for DecoderError

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 DecoderError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<Error> for DecoderError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<ShapeError> for DecoderError

fn from(err: ShapeError) -> Self

Converts to this type from the input type.
