Enum TensorViewMut 

pub enum TensorViewMut<'a> {
    F32(TypedTensorViewMut<'a, f32>),
    F64(TypedTensorViewMut<'a, f64>),
    I32(TypedTensorViewMut<'a, i32>),
    I64(TypedTensorViewMut<'a, i64>),
    Bool(TypedTensorViewMut<'a, bool>),
    C32(TypedTensorViewMut<'a, Complex<f32>>),
    C64(TypedTensorViewMut<'a, Complex<f64>>),
}

Dynamic mutable borrowed tensor view.

TensorViewMut is the mutable counterpart to TensorView. It keeps the dtype erased while preserving the typed mutable view’s shape, strides, and offset metadata.

Examples

use tenferro_tensor::{DType, TensorViewMut, TypedTensorViewMut};

let mut data = [1.0_f64, 2.0];
let view = TensorViewMut::F64(TypedTensorViewMut::from_slice([2], [1], 0, &mut data)?);
assert_eq!(view.dtype(), DType::F64);
