Enum MatrixTensorConversionError 

pub enum MatrixTensorConversionError {
    Rank {
        shape: Vec<usize>,
    },
    HostBuffer {
        message: String,
    },
}

Error returned when converting a [TypedTensor] into a Matrix.

Use this when accepting dynamic tensor-shaped values at a dense-matrix boundary. It reports whether conversion failed because the tensor was not a rank-2 matrix or because its host buffer could not be consumed.

Examples

use tenferro::TypedTensor;
use tensor4all_tensorbackend::Matrix;

let tensor = TypedTensor::from_vec_col_major(vec![2, 1, 1], vec![1.0_f64, 2.0])?;
let err = Matrix::try_from_typed_tensor(tensor).unwrap_err();
assert!(err.to_string().contains("rank-2 tensor"));

Variants

Rank

The input tensor rank was not two.

Fields

shape: Vec<usize>

Tensor shape that failed the rank check.

HostBuffer

The tensor did not contain an owned host buffer that can be consumed.

Fields

message: String

Backend conversion error reported by tenferro.

Trait Implementations

impl Debug for MatrixTensorConversionError

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

Formats the value using the given formatter.

impl Display for MatrixTensorConversionError

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

Formats the value using the given formatter.

impl Error for MatrixTensorConversionError

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>)
