}

Sealed trait for scalar types supported by the core tensor data model.

Examples

use tenferro_tensor_core::{DType, TensorScalar};

assert_eq!(f64::dtype(), DType::F64);
assert_eq!(num_complex::Complex64::dtype(), DType::C64);

Required Associated Types

type Real: TensorScalar

Real-valued counterpart of this scalar type.

Required Methods

fn dtype() -> DType

Return the scalar dtype tag.

Examples

use tenferro_tensor_core::{DType, TensorScalar};

assert_eq!(i64::dtype(), DType::I64);

fn into_tensor(shape: ShapeVec, data: Vec<Self>) -> Result<Tensor>

Build a dynamic tensor from validated column-major data.

Examples

use tenferro_tensor_core::{DType, ShapeVec, TensorScalar};

let tensor = <f64 as TensorScalar>::into_tensor(ShapeVec::from_slice(&[1]), vec![2.0])?;
assert_eq!(tensor.dtype(), DType::F64);

fn tensor_slice(tensor: &Tensor) -> Option<&[Self]>

fn tensor_mut_slice(tensor: &mut Tensor) -> Option<&mut [Self]>

fn into_typed(tensor: Tensor) -> Option<HostTensor<Self>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
