Struct BindGroupLayoutEntry 

pub struct BindGroupLayoutEntry {
    pub binding: u32,
    pub visibility: ShaderStages,
    pub ty: BindGroupEntryType,
}

A single entry inside a GpuBindGroupLayoutDescriptor.

Together these describe one slot of the bind group layout used by a render / compute pipeline. The visibility field names the shader stages that can read the binding as ShaderStage values combined with |; a hand-written 0x1 / 0x2 / 0x4 there silently produced a binding the shader could not see.

Fields

binding: u32

The binding slot (matches @binding(N) in the shader).

visibility: ShaderStages

The shader stages that can read this binding. Combine several with |, e.g. ShaderStage::Vertex | ShaderStage::Fragment.

ty: BindGroupEntryType

The resource kind bound at this slot.

Implementations

impl BindGroupLayoutEntry

pub fn uniform<V: Into<ShaderStages>>(binding: u32, visibility: V) -> Self

Convenience constructor for a uniform-buffer binding slot.

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.

pub fn storage<V: Into<ShaderStages>>( binding: u32, visibility: V, read_only: bool, ) -> Self

Convenience constructor for a storage-buffer binding slot.

read_only = true selects read-only-storage (matches var<storage, read>); read_only = false selects storage (matches var<storage, read_write>).

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.
• bool - Whether shaders may only read from the buffer.

pub fn texture<V: Into<ShaderStages>>( binding: u32, visibility: V, sample_type: &str, ) -> Self

Convenience constructor for a sampled texture binding slot.

sample_type must be one of "float", "unfilterable-float", "depth", "sint", "uint".

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.
• &str - The texel sample type name used by the shader.

pub fn texture_multisampled<V: Into<ShaderStages>>( binding: u32, visibility: V, sample_type: &str, ) -> Self

Convenience constructor for a multisampled sampled texture binding slot.

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.
• &str - The texel sample type name used by the shader.

pub fn storage_texture<V: Into<ShaderStages>>( binding: u32, visibility: V, format: &str, read_only: bool, ) -> Self

Convenience constructor for a storage-texture binding slot.

format is a GpuTextureFormat string such as "rgba8unorm" or "r32float".

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.
• &str - The storage texture format name.
• bool - Whether shaders may only read from the texture.

pub fn sampler<V: Into<ShaderStages>>(binding: u32, visibility: V) -> Self

Convenience constructor for a filtering sampler binding slot.

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.

pub fn sampler_non_filtering<V: Into<ShaderStages>>( binding: u32, visibility: V, ) -> Self

Convenience constructor for a non-filtering sampler binding slot.

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.

pub fn sampler_comparison<V: Into<ShaderStages>>( binding: u32, visibility: V, ) -> Self

Convenience constructor for a comparison sampler binding slot.

Arguments

• u32 - The binding index within the bind group.
• V - The shader stages that can access the slot. Either a lone ShaderStage, or a ShaderStages mask built with | when more than one stage reads this binding.
