Enum TextureUsage 

pub enum TextureUsage {
    CopySource,
    CopyDestination,
    TextureBinding,
    StorageBinding,
    RenderAttachment,
}

One legal use of a GPU texture, as declared in GpuTextureDescriptor.usage.

Like BufferUsage, the underlying WebGPU field is a bitmask and the renderer ORs the selected variants together at the call site. A render target needs RenderAttachment; a sampled texture needs TextureBinding; a write-once compute output needs StorageBinding.

Variants

CopySource

The texture may be the source of a texture-to-texture or texture-to-buffer copy.

CopyDestination

The texture may be the destination of queue.writeTexture or of a texture-to-texture copy.

TextureBinding

The texture is sampled through a texture_2d<f32> binding.

StorageBinding

The texture is written through a texture_storage_2d<...> binding.

RenderAttachment

The texture is bound as a color, depth, or stencil attachment of a render pass.

Implementations

impl TextureUsage

The GPUTextureUsage bit one use occupies.

The texture-side counterpart of BufferUsage::usage_bit. Note that the buffer and texture families share their variant names but not their values - CopySource is 4 for a buffer and 1 for a texture - which is why the two tables are separate.

pub fn usage_bit(self) -> u32

The GPUTextureUsage bit this use occupies.

Returns

• u32 - The bit this use occupies in a GpuTextureDescriptor usage; combine several with |.

Trait Implementations

impl BitOr for TextureUsage

Combines two texture uses into the bitmask a GpuTextureDescriptor expects.

The texture counterpart of the | operator on BufferUsage, with the same single-source-of-truth rationale.

type Output = u32

The combined usage bitmask.

fn bitor(self, rhs: Self) -> Self::Output

Combines two texture uses into their usage bitmask.

Arguments

• Self - The right-hand use.

Returns

• Self::Output - The bitmask carrying both uses.

impl Clone for TextureUsage

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TextureUsage

impl Debug for TextureUsage

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

Formats the value using the given formatter.

impl Eq for TextureUsage

impl Hash for TextureUsage

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TextureUsage

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

Equality operator ==.

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

Inequality operator !=.
