Struct TensorViewMut 

pub struct TensorViewMut<'a, T: TensorElement> { /* private fields */ }

Mutable view into tensor data (zero-copy)

Provides read-write access to tensor data without copying. Only one mutable view can exist at a time (exclusive borrowing).

Examples

let mut tensor = Tensor::from_vec(vec![1.0, 2.0, 3.0, 4.0], &[2, 2])?;
let mut view = tensor.view_mut();
view.fill(0.0);

Implementations

impl<'a, T: TensorElement> TensorViewMut<'a, T>

pub fn new( data: &'a mut [T], shape: Shape, strides: Vec<usize>, offset: usize, ) -> Self

Create a new mutable tensor view from raw parts

Arguments

• data - Mutable reference to underlying buffer
• shape - Shape of the view
• strides - Strides for indexing
• offset - Offset into parent buffer

pub fn shape(&self) -> &Shape

Get the shape of the view

pub fn strides(&self) -> &[usize]

Get the strides of the view

pub fn len(&self) -> usize

Get the number of elements in the view

pub fn is_empty(&self) -> bool

Check if the view is empty

pub fn data(&self) -> &[T]

Get a reference to the underlying data slice

pub fn data_mut(&mut self) -> &mut [T]

Get a mutable reference to the underlying data slice

For in-place SIMD operations, this provides direct buffer access.

pub fn is_contiguous(&self) -> bool

Check if the view is contiguous in memory

pub fn get(&self, index: usize) -> Result<&T>

Get element at flat index (zero-copy)

pub fn get_mut(&mut self, index: usize) -> Result<&mut T>

Get mutable element at flat index (zero-copy)

pub fn fill(&mut self, value: T)

where T: Copy,

Fill the view with a value (in-place)

Arguments

• value - Value to fill with

Examples

let mut view = tensor.view_mut();
view.fill(0.0);

pub fn iter(&self) -> TensorViewIter<'_, T>

Create an iterator over the view’s elements

pub fn iter_mut(&mut self) -> TensorViewIterMut<'_, T>

Create a mutable iterator over the view’s elements

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

Formats the value using the given formatter.
