Errors that can occur while accessing or converting TensorData.

Variants

StorageAccess(AccessError)

Host access to the underlying storage failed.

InvalidRepresentation(CheckedCastError)

The stored bytes aren’t a valid representation of the requested element type.

DTypeMismatch

The stored dtype doesn’t match the requested dtype.

Fields

expected: DType

The expected storage DType.

actual: DType

The actual storage DType.

UnsupportedConversion

Unsupported data conversion.

Fields

from: DType

The source DType.

to: DType

The destination DType.

ElementCountMismatch

The byte storage doesn’t match the number of elements described by the shape.

Fields

expected: usize

The number of elements described by the shape.

actual: usize

The number of elements present in storage.

InvalidByteLength

The byte storage length doesn’t match the size implied by the shape and dtype.

Fields

shape: Shape

The shape describing the tensor.

dtype: DType

The storage DType.

len: usize

The number of bytes present in storage.

Trait Implementations

impl Debug for DataError

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

Formats the value using the given formatter.

impl Display for DataError

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

Formats the value using the given formatter.

impl Eq for DataError

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<AccessError> for DataError

fn from(source: AccessError) -> DataError

Converts to this type from the input type.

impl From<DataError> for TensorReadError

fn from(source: DataError) -> TensorReadError

Converts to this type from the input type.

impl PartialEq for DataError

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