Error type for contraction preparation.

Variants

NoCommonIndices

No common indices found for contraction.

DimensionMismatch

Dimension mismatch for a common index.

Fields

pos_a: usize

Position in the first tensor.

pos_b: usize

Position in the second tensor.

dim_a: usize

Dimension in the first tensor.

dim_b: usize

Dimension in the second tensor.

DuplicateAxis

Duplicate axis specified in contraction.

Fields

tensor: &'static str

Which tensor has the duplicate (“self” or “other”).

pos: usize

Position of the duplicate axis.

IndexNotFound

Index not found in tensor.

Fields

tensor: &'static str

Which tensor the index was not found in.

BatchContractionNotImplemented

Batch contraction not yet implemented.

Trait Implementations

impl Clone for ContractionError

fn clone(&self) -> ContractionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContractionError

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

Formats the value using the given formatter.

impl Display for ContractionError

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

Formats the value using the given formatter.

impl Error for ContractionError

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 ContractionError

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