Struct EfD3d11Layout 

#[repr(C)]
pub struct EfD3d11Layout {
    pub dxgi_format: u32,
    pub texture_width: u32,
    pub texture_height: u32,
    pub bytes_per_texel: u32,
    pub gl_internal_format: u32,
}

The D3D11 texture behind a Windows texture tensor.

The scalar block ef_tensor_d3d11_layout fills, the same shape as ef_tensor_plane and ef_tensor_view_origin – one library reading a tensor it did not mint. Mirrors edgefirst_tensor::d3d11_layout:: D3d11ImageLayout.

The dimensions are the texture’s, in texels and rows, not the image’s in pixels: a semi-planar image is one texture whose row count covers both planes, and a YUYV image is one texel per two pixels, so texture_width/texture_height do not match ef_tensor_shape for either. Read the image’s own dimensions from the shape.

For a semi-planar format (nv12, nv16, nv24) texture_width is the driver’s row pitch – at least even(width), and on a discrete adapter commonly more (128 bytes on NVIDIA, so a 64-wide NV12 image is a 128-wide texture). It is the pitch the combined plane’s rows are spaced by and the width a sampler must address the texture at. Never derive it from the image width: read this field, or ef_tensor_row_stride, which carries the same number.

By-value and frozen forever: a consumer bakes this size and these offsets into its call sites, so the struct evolves by a suffixed successor, never by an in-place edit. d3d11_layout_is_pinned and the C golden in tensor-capi/tests/c/test_layout_goldens.c hold both sides to it.

Fields

dxgi_format: u32

DXGI_FORMAT the texture was created with.

texture_width: u32

Texture width in texels.

texture_height: u32

Texture height in rows.

bytes_per_texel: u32

Bytes per texel of dxgi_format.

gl_internal_format: u32

The GL internal format an importer binds this texture as; 0 when the format has no GL equivalent.
