Public scalar element types supported by tensor4all dense/diag constructors.

Implemented for f32, f64, Complex32, and Complex64.

Examples

use tensor4all_tensorbackend::TensorElement;

let t = f64::dense_native_tensor_from_col_major(&[1.0, 2.0], &[2]).unwrap();
assert_eq!(t.shape(), &[2]);

let vals = f64::dense_values_from_native_col_major(&t).unwrap();
assert_eq!(vals, vec![1.0, 2.0]);

Required Methods

fn dense_native_tensor_from_col_major( data: &[Self], dims: &[usize], ) -> Result<Tensor, Error>

Build a dense native tensor from column-major data.

Errors

Returns an error when the data length does not match the dimensions (a /// shape mismatch) or the backend conversion fails.

fn diag_native_tensor_from_col_major( data: &[Self], logical_rank: usize, ) -> Result<Tensor, Error>

Build a diagonal native tensor from column-major diagonal payload data.

Errors

Returns an error when the diagonal payload is incompatible (a shape /// mismatch) or the backend conversion fails.

fn scalar_native_tensor(value: Self) -> Result<Tensor, Error>

Build a rank-0 native tensor.

Errors

Returns an error when the scalar cannot be converted (a dtype mismatch or /// backend failure).

fn dense_values_from_native_col_major( tensor: &Tensor, ) -> Result<Vec<Self>, Error>

Materialize dense column-major values from a native tensor.

Errors

Returns an error when the native tensor cannot be materialized (a dtype /// mismatch or backend failure).

fn diag_values_from_native_temp(tensor: &Tensor) -> Result<Vec<Self>, Error>

Materialize diagonal values from a dense native tensor.

Errors

Returns an error when the native tensor cannot be materialized (a dtype /// mismatch or backend failure).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
