Struct BindGroupLayoutEntry

pub struct BindGroupLayoutEntry {
    pub binding: u32,
    pub visibility: ShaderStages,
    pub ty: BindingType,
    pub count: Option<NonZeroU32>,
}

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.

ty: BindingType

The type of the binding

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:

• Size must be of value 1 or greater.
• When ty == BindingType::Texture, Features::TEXTURE_BINDING_ARRAY must be supported.
• When ty == BindingType::Sampler, Features::TEXTURE_BINDING_ARRAY must be supported.
• When ty == BindingType::Buffer, Features::BUFFER_BINDING_ARRAY must be supported.
• When ty == BindingType::Buffer and ty.ty == BufferBindingType::Storage, Features::STORAGE_RESOURCE_BINDING_ARRAY must be supported.
• When ty == BindingType::StorageTexture, 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.

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 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.
