Expand description
Subresource range within an image
Fields§
§aspect: TextureAspect
Aspect of the texture. Color textures must be TextureAspect::All
.
base_mip_level: u32
Base mip level.
mip_level_count: Option<u32>
Mip level count.
If Some(count)
, base_mip_level + count
must be less or equal to underlying texture mip count.
If None
, considered to include the rest of the mipmap levels, but at least 1 in total.
base_array_layer: u32
Base array layer.
array_layer_count: Option<u32>
Layer count.
If Some(count)
, base_array_layer + count
must be less or equal to the underlying array count.
If None
, considered to include the rest of the array layers, but at least 1 in total.
