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<NonZeroU32>

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<NonZeroU32>

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.

impl ImageSubresourceRange

source

pub fn is_full_resource(&self, mip_levels: u32, array_layers: u32) -> bool

Returns if the given range represents a full resource, with a texture of the given layer count and mip count.

    aspect: wgpu::TextureAspect::All,
    base_mip_level: 0,
    mip_level_count: None,
    base_array_layer: 0,
    array_layer_count: None,
};
assert_eq!(range_none.is_full_resource(5, 10), true);

let range_some = wgpu::ImageSubresourceRange {
    aspect: wgpu::TextureAspect::All,
    base_mip_level: 0,
    mip_level_count: NonZeroU32::new(5),
    base_array_layer: 0,
    array_layer_count: NonZeroU32::new(10),

let range_mixed = wgpu::ImageSubresourceRange {
    aspect: wgpu::TextureAspect::All,
    base_mip_level: 0,
    // Only partial resource
    mip_level_count: NonZeroU32::new(3),
    base_array_layer: 0,

};
assert_eq!(range_mixed.is_full_resource(5, 10), false);
source

pub fn mip_range<L, V>( &self, texture_desc: &TextureDescriptor<L, V> ) -> Range<u32>
