Module d3d11_layout 

(PixelFormat, DType, width, height) -> D3D11 texture layout.

Compiled on every platform so the table is unit-tested on every CI lane; only the allocator that consumes it is Windows-only. Single source of truth for which DXGI format and texture geometry back each HAL image format; the image crate reads gl_internal_format when it builds the EGL_ANGLE_image_d3d11_texture attribute list.

Structs

D3d11ImageLayout

One texture’s format and geometry for a HAL image. texture_width and texture_height are texels and rows, not image pixels: the packed rows fold several pixels or several planes into one texel, and a semi-planar row is the image’s row stride rather than its width.

Functions

image_d3d11_layout

The D3D11 texture that backs format/dtype at width x height, or None when the format has no zero-copy texture layout (it then falls to PBO or Mem in the allocation chain).
