Enum BindlessResourceType 

pub enum BindlessResourceType {
    None,
    Buffer,
    SamplerFiltering,
    SamplerNonFiltering,
    SamplerComparison,
    Texture1d,
    Texture2d,
    Texture2dArray,
    Texture3d,
    TextureCube,
    TextureCubeArray,
    DataBuffer,
}

The type of potentially-bindless resource.

Variants

None

No bindless resource.

This is used as a placeholder to fill holes in the BindlessDescriptor::resources list.

Buffer

A storage buffer.

SamplerFiltering

A filtering sampler.

SamplerNonFiltering

A non-filtering sampler (nearest neighbor).

SamplerComparison

A comparison sampler (typically used for shadow maps).

Texture1d

A 1D texture.

Texture2d

A 2D texture.

Texture2dArray

A 2D texture array.

Note that this differs from a binding array. 2D texture arrays must all have the same size and format.

Texture3d

A 3D texture.

TextureCube

A cubemap texture.

TextureCubeArray

A cubemap texture array.

Note that this differs from a binding array. Cubemap texture arrays must all have the same size and format.

DataBuffer

Multiple instances of plain old data concatenated into a single buffer.

This corresponds to the #[data] declaration in crate::render_resource::AsBindGroup.

Note that this resource doesn’t itself map to a GPU-level binding resource and instead depends on the MaterialBindGroupAllocator to create a binding resource for it.

Implementations

impl BindlessResourceType

pub fn binding_number(&self) -> Option<&'static BindingNumber>

Returns the binding number for the common array of this resource type.

For example, if you pass BindlessResourceType::Texture2d, this will return 5, in order to match the @group(2) @binding(5) var bindless_textures_2d: binding_array<texture_2d<f32>> declaration in bindless.wgsl.

Not all resource types have fixed binding numbers. If you call Self::binding_number on such a resource type, it returns None.

Note that this returns a static reference to the binding number, not the binding number itself. This is to conform to an idiosyncratic API in wgpu whereby binding numbers for binding arrays are taken by &u32 reference, not by u32 value.

Trait Implementations

impl Clone for BindlessResourceType

fn clone(&self) -> BindlessResourceType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindlessResourceType

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

Formats the value using the given formatter.

impl From<SamplerBindingType> for BindlessResourceType

fn from(sampler_binding_type: SamplerBindingType) -> BindlessResourceType

Converts to this type from the input type.

impl From<TextureViewDimension> for BindlessResourceType

fn from(texture_view_dimension: TextureViewDimension) -> BindlessResourceType

Converts to this type from the input type.

impl Hash for BindlessResourceType

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

where __H: Hasher,

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 Ord for BindlessResourceType

fn cmp(&self, other: &BindlessResourceType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BindlessResourceType

fn eq(&self, other: &BindlessResourceType) -> 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.

impl PartialOrd for BindlessResourceType

fn partial_cmp(&self, other: &BindlessResourceType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
