Errors from tensor operations.

Variants

ShapeMismatch

Shape mismatch for an operation.

Fields

expected: Vec<usize>

Expected shape.

got: Vec<usize>

Actual shape.

DataLengthMismatch

Data length doesn’t match shape.

Fields

len: usize

Data length.

shape: Vec<usize>

Expected shape.

product: usize

Product of shape dims.

InvalidSubscript(String)

Invalid einsum subscript string.

ContractionDimensionMismatch

Contracted dimensions don’t match.

Fields

index: char

Index label.

size_a: usize

Size in tensor A.

size_b: usize

Size in tensor B.

Trait Implementations

impl Debug for TensorError

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

Formats the value using the given formatter.

impl Display for TensorError

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

Formats the value using the given formatter.

impl Error for TensorError

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.
