}

Describes a single binding inside a bind group.

Corresponds to WebGPU GPUBindGroupLayoutEntry.

Fields

binding: u32

Binding index. Must match shader index and be unique inside a BindGroupLayout. A binding of index 1, would be described as @group(0) @binding(1) in shaders.

visibility: ShaderStages

Which shader stages can see this binding.

buffer: Option<BufferBindingLayout>

sampler: Option<SamplerBindingLayout>

texture: Option<TextureBindingLayout>

storage_texture: Option<StorageTextureBindingLayout>

external_texture: Option<ExternalTextureBindingLayout>

acceleration_structure: Option<AccelerationStructureBindingLayout>

count: Option<NonZeroU32>

If the binding is an array of multiple resources. Corresponds to binding_array<T> in the shader.

When this is Some the following validation applies:

• Count must be of value 1 or greater, this corresponds to the length of the array of resources that will be bound.
• When ty == BindingType::Texture, wgt::Features::TEXTURE_BINDING_ARRAY must be supported.
• When ty == BindingType::Sampler, wgt::Features::TEXTURE_BINDING_ARRAY must be supported.
• When ty == BindingType::Buffer, wgt::Features::BUFFER_BINDING_ARRAY must be supported.
• When ty == BindingType::Buffer and ty.ty == BufferBindingType::Storage, wgt::Features::STORAGE_RESOURCE_BINDING_ARRAY must be supported.
• When ty == BindingType::StorageTexture, wgt::Features::STORAGE_RESOURCE_BINDING_ARRAY must be supported.
• When any binding in the group is an array, no BindingType::Buffer in the group may have has_dynamic_offset == true
• When any binding in the group is an array, no BindingType::Buffer in the group may have ty.ty == BufferBindingType::Uniform.
• If wgt::Features::PARTIALLY_BOUND_BINDING_ARRAY is enabled, the specified count becomes the upper bound instead.

Trait Implementations

impl Clone for BindGroupLayoutEntry

fn clone(&self) -> BindGroupLayoutEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindGroupLayoutEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BindGroupLayoutEntry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<BindGroupLayoutEntry> for BindGroupLayoutEntry

fn from(val: BindGroupLayoutEntry) -> Self

Converts to this type from the input type.

impl Hash for BindGroupLayoutEntry

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 BindGroupLayoutEntry

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryInto<BindGroupLayoutEntry> for BindGroupLayoutEntry

type Error = CreateBindGroupLayoutError

The type returned in the event of a conversion error.

fn try_into(self) -> Result<BindGroupLayoutEntry, Self::Error>

Performs the conversion.
