Struct ViewOrigin 

pub struct ViewOrigin {
    pub parent_width: usize,
    pub parent_height: usize,
    pub parent_row_stride: usize,
    pub x: usize,
    pub y: usize,
}

The parent image a view/batch sub-region was carved from, snapshotted at the time the view was created.

A view shares the parent’s BufferIdentity and addresses a sub-rectangle of it. The GL backend keys its EGLImage import on the parent geometry (so all sibling views of one buffer collapse to a single import) and renders each view as a glViewport+glScissor ROI at (x, y, width, height) within that parent — the view is render state, never a distinct import. parent_width/ parent_height are the parent’s logical pixel dimensions; x/y are this view’s top-left origin within the parent (pixels). Nested views compose: the snapshot always names the root parent, with offsets accumulated.

Fields

parent_width: usize

Logical width of the root parent image, in pixels.

parent_height: usize

Logical height of the root parent image, in pixels. For a batch(n) view of an [N, H, W, C] tensor this is N * H (the tiles stack vertically in the shared buffer).

parent_row_stride: usize

The parent’s row stride in bytes. The GL backend keys its EGLImage import/cache and pitch on this — NOT on the view’s own row_stride, which a single-row view sets tight (for map-span safety). Using the parent stride keeps the import pitch parent-consistent so single-row and multi-row sibling views collapse onto the same parent import.

x: usize

This view’s top-left x origin within the root parent, in pixels.

y: usize

This view’s top-left y origin within the root parent, in pixels.

Trait Implementations

impl Clone for ViewOrigin

fn clone(&self) -> ViewOrigin

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ViewOrigin

impl Debug for ViewOrigin

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

Formats the value using the given formatter.

impl Eq for ViewOrigin

impl PartialEq for ViewOrigin

fn eq(&self, other: &ViewOrigin) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
