Struct ArrayView3 

pub struct ArrayView3<'a, T> { /* private fields */ }

Immutable 3D array view.

Implementations

impl<'a, T> ArrayView3<'a, T>

pub fn new( data: &'a [T], shape: [usize; 3], strides: [isize; 3], offset: isize, ) -> Result<Self>

Create a checked immutable view.

pub fn shape(&self) -> [usize; 3]

Shape as [dim0, dim1, dim2].

pub fn strides(&self) -> [isize; 3]

Strides in elements.

pub fn len(&self) -> usize

Number of logical elements.

pub fn is_empty(&self) -> bool

Whether the view is empty.

pub fn is_contiguous(&self) -> bool

Whether the view is compact row-major contiguous.

pub fn as_slice(&self) -> Option<&'a [T]>

Borrow the backing slice if this view covers it contiguously.

pub fn get(&self, i: usize, j: usize, k: usize) -> Option<&'a T>

Get an element reference.

pub fn matrix_at(&self, axis: usize, index: usize) -> Result<ArrayView2<'a, T>>

Extract a 2D matrix view by fixing one axis.

pub fn for_each_matrix( &self, axis: usize, f: impl FnMut(usize, ArrayView2<'a, T>) -> Result<()>, ) -> Result<()>

Visit each 2D matrix slice along axis in order.
