Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

EmptyInput

At least one ordered part is required.

InvalidTensorShape

Tensor identities must be non-scalar and have non-zero dimensions.

Fields

shape: Vec<usize>

Invalid logical dimensions.

IncompatiblePayload

A modality cannot consume the selected primary payload kind.

Fields

modality: InputModality

Declared modality.

payload: InputPayloadKind

Declared payload kind.

IncompatibleMetadata

Metadata belongs to a different modality.

Fields

modality: InputModality

Declared modality.

key: InputMetadataKey

Metadata key.

DuplicateMetadata

A typed metadata key occurred more than once.

Fields

key: InputMetadataKey

Duplicated key.

IncompatibleExtent

A host execution extent belongs to a different modality.

Fields

modality: InputModality

Declared modality.

extent: InputExtent

Incompatible extent.

DuplicateExtent

An execution extent kind occurred more than once.

Fields

extent: InputExtent

Duplicated extent.

MissingMetadata

Family policy required absent metadata.

Fields

part: usize

Ordered part index.

modality: InputModality

Part modality.

key: InputMetadataKey

Required key.

InvalidWireValue

A descriptor tag was not recognized.

Fields

field: &'static str

Descriptor field.

value: u32

Invalid value.

TruncatedWireDescriptor(&'static str)

Descriptor ended before the announced data was present.

InvalidWireRank(usize)

Descriptor carried an unsupported tensor rank.

InvalidMetadataCount(usize)

A part advertised more metadata keys than the closed vocabulary contains.

InvalidExtentCount(usize)

A part advertised more host extents than the closed vocabulary contains.

TrailingWireValues

Descriptor has data after the complete identity.

WireValueOverflow(&'static str)

A host value cannot be represented by the u32 wire format.

WireValueCount

The number of received tensors does not match the identity.

Fields

expected: usize

Expected payload and metadata tensor count.

actual: usize

Received tensor count.

WireIdentityMismatch

Received tensor shape or dtype disagrees with the advertised identity.

EncodedRuntimeDtype(String)

Encoded/quantized checkpoint storage is not a runtime tensor dtype.

BackendTensorIdentity(String)

A backend could not describe a prepared tensor without materializing it.

Trait Implementations

impl Clone for PreparedInputError

fn clone(&self) -> PreparedInputError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PreparedInputError

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

Formats the value using the given formatter.

impl Display for PreparedInputError

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

impl Eq for PreparedInputError

impl Error for PreparedInputError

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 PartialEq for PreparedInputError

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

Equality operator ==.

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

Inequality operator !=.
