Errors that can occur in TensorTrain operations.

Variants

Empty

Tensor train is empty (has no tensors).

SiteOutOfBounds

Site index is out of bounds.

Fields

site: usize

The requested site index.

length: usize

The total number of sites in the tensor train.

BondDimensionMismatch

Bond dimension mismatch between adjacent tensors.

Fields

site: usize

The site index where the mismatch occurred.

left_dim: usize

The right bond dimension of the left tensor.

right_dim: usize

The left bond dimension of the right tensor.

NoOrthogonalityCenter

Tensor train does not have a well-defined orthogonality center.

Fields

start: usize

The start of the orthogonality limits range.

end: usize

The end of the orthogonality limits range.

InvalidStructure

Invalid tensor structure for tensor train.

Fields

message: String

A description of the structural issue.

Factorize(FactorizeError)

Factorization error.

OperationError

General operation error.

Fields

message: String

A description of the operation error.

Trait Implementations

impl Debug for TensorTrainError

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

Formats the value using the given formatter.

impl Display for TensorTrainError

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

Formats the value using the given formatter.

impl Error for TensorTrainError

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<FactorizeError> for TensorTrainError

fn from(source: FactorizeError) -> Self

Converts to this type from the input type.
