Struct FeaturesWGPU

#[repr(transparent)]
pub struct FeaturesWGPU(<FeaturesWGPU as PublicFlags>::Internal);

Features that are not guaranteed to be supported.

These are extension features supported by wgpu when targeting native. For all features see Features

If you want to use a feature, you need to first verify that the adapter supports the feature. If the adapter does not support the feature, requesting a device with it enabled will panic.

Corresponds to WebGPU GPUFeatureName.

Implementations

impl FeaturesWGPU

pub const SHADER_FLOAT32_ATOMIC: FeaturesWGPU = _

Allows shaders to use f32 atomic load, store, add, sub, and exchange.

Supported platforms:

• Metal (with MSL 3.0+ and Apple7+/Mac2)
• Vulkan (with VK_EXT_shader_atomic_float)

This is a native only feature.

pub const TEXTURE_FORMAT_16BIT_NORM: FeaturesWGPU = _

Enables normalized 16-bit texture formats.

Supported platforms:

• Vulkan
• DX12
• Metal

This is a native only feature.

pub const TEXTURE_COMPRESSION_ASTC_HDR: FeaturesWGPU = _

Enables ASTC HDR family of compressed textures.

Compressed textures sacrifice some quality in exchange for significantly reduced bandwidth usage.

Support for this feature guarantees availability of [TextureUsages::COPY_SRC | TextureUsages::COPY_DST | TextureUsages::TEXTURE_BINDING] for ASTC formats with the HDR channel type. Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES may enable additional usages.

Supported Platforms:

• Metal
• Vulkan
• OpenGL

This is a native only feature.

pub const TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES: FeaturesWGPU = _

Enables device specific texture format features.

See TextureFormatFeatures for a listing of the features in question.

By default only texture format properties as defined by the WebGPU specification are allowed. Enabling this feature flag extends the features of each format to the ones supported by the current device. Note that without this flag, read/write storage access is not allowed at all.

This extension does not enable additional formats.

This is a native only feature.

pub const PIPELINE_STATISTICS_QUERY: FeaturesWGPU = _

Enables use of Pipeline Statistics Queries. These queries tell the count of various operations performed between the start and stop call. Call RenderPass::begin_pipeline_statistics_query to start a query, then call RenderPass::end_pipeline_statistics_query to stop one.

They must be resolved using CommandEncoder::resolve_query_set into a buffer. The rules on how these resolve into buffers are detailed in the documentation for PipelineStatisticsTypes.

Supported Platforms:

• Vulkan
• DX12

This is a native only feature with a proposal for the web.

pub const TIMESTAMP_QUERY_INSIDE_ENCODERS: FeaturesWGPU = _

Allows for timestamp queries directly on command encoders.

Implies Features::TIMESTAMP_QUERY is supported.

Additionally allows for timestamp writes on command encoders using CommandEncoder::write_timestamp.

Supported platforms:

• Vulkan
• DX12
• Metal

This is a native only feature.

pub const TIMESTAMP_QUERY_INSIDE_PASSES: FeaturesWGPU = _

Allows for timestamp queries directly on command encoders.

Implies Features::TIMESTAMP_QUERY & Features::TIMESTAMP_QUERY_INSIDE_ENCODERS is supported.

Additionally allows for timestamp queries to be used inside render & compute passes using:

• RenderPass::write_timestamp
• ComputePass::write_timestamp

Supported platforms:

• Vulkan
• DX12
• Metal (AMD & Intel, not Apple GPUs)

This is generally not available on tile-based rasterization GPUs.

This is a native only feature with a proposal for the web.

pub const MAPPABLE_PRIMARY_BUFFERS: FeaturesWGPU = _

Webgpu only allows the MAP_READ and MAP_WRITE buffer usage to be matched with COPY_DST and COPY_SRC respectively. This removes this requirement.

This is only beneficial on systems that share memory between CPU and GPU. If enabled on a system that doesn’t, this can severely hinder performance. Only use if you understand the consequences.

Supported platforms:

• Vulkan
• DX12
• Metal

This is a native only feature.

pub const TEXTURE_BINDING_ARRAY: FeaturesWGPU = _

Allows the user to create uniform arrays of textures in shaders:

ex.

• var textures: binding_array<texture_2d<f32>, 10> (WGSL)
• uniform texture2D textures[10] (GLSL)

If Features::STORAGE_RESOURCE_BINDING_ARRAY is supported as well as this, the user may also create uniform arrays of storage textures.

ex.

• var textures: array<texture_storage_2d<r32float, write>, 10> (WGSL)
• uniform image2D textures[10] (GLSL)

This capability allows them to exist and to be indexed by dynamically uniform values.

Supported platforms:

• DX12
• Metal (with MSL 2.0+ on macOS 10.13+)
• Vulkan

This is a native only feature.

pub const BUFFER_BINDING_ARRAY: FeaturesWGPU = _

Allows the user to create arrays of buffers in shaders:

ex.

• var<uniform> buffer_array: array<MyBuffer, 10> (WGSL)
• uniform myBuffer { ... } buffer_array[10] (GLSL)

This capability allows them to exist and to be indexed by dynamically uniform values.

If Features::STORAGE_RESOURCE_BINDING_ARRAY is supported as well as this, the user may also create arrays of storage buffers.

ex.

• var<storage> buffer_array: array<MyBuffer, 10> (WGSL)
• buffer myBuffer { ... } buffer_array[10] (GLSL)

Supported platforms:

• Vulkan

This is a native only feature.

pub const STORAGE_RESOURCE_BINDING_ARRAY: FeaturesWGPU = _

Allows the user to create uniform arrays of storage buffers or textures in shaders, if resp. Features::BUFFER_BINDING_ARRAY or Features::TEXTURE_BINDING_ARRAY is supported.

This capability allows them to exist and to be indexed by dynamically uniform values.

Supported platforms:

• Metal (with MSL 2.2+ on macOS 10.13+)
• Vulkan

This is a native only feature.

pub const SAMPLED_TEXTURE_AND_STORAGE_BUFFER_ARRAY_NON_UNIFORM_INDEXING: FeaturesWGPU = _

Allows shaders to index sampled texture and storage buffer resource arrays with dynamically non-uniform values:

ex. texture_array[vertex_data]

In order to use this capability, the corresponding GLSL extension must be enabled like so:

#extension GL_EXT_nonuniform_qualifier : require

and then used either as nonuniformEXT qualifier in variable declaration:

ex. layout(location = 0) nonuniformEXT flat in int vertex_data;

or as nonuniformEXT constructor:

ex. texture_array[nonuniformEXT(vertex_data)]

WGSL and HLSL do not need any extension.

Supported platforms:

• DX12
• Metal (with MSL 2.0+ on macOS 10.13+)
• Vulkan 1.2+ (or VK_EXT_descriptor_indexing)’s shaderSampledImageArrayNonUniformIndexing & shaderStorageBufferArrayNonUniformIndexing feature)

This is a native only feature.

pub const STORAGE_TEXTURE_ARRAY_NON_UNIFORM_INDEXING: FeaturesWGPU = _

Allows shaders to index storage texture resource arrays with dynamically non-uniform values:

ex. texture_array[vertex_data]

Supported platforms:

• DX12
• Metal (with MSL 2.0+ on macOS 10.13+)
• Vulkan 1.2+ (or VK_EXT_descriptor_indexing)’s shaderStorageTextureArrayNonUniformIndexing feature)

This is a native only feature.

pub const PARTIALLY_BOUND_BINDING_ARRAY: FeaturesWGPU = _

Allows the user to create bind groups containing arrays with less bindings than the BindGroupLayout.

Supported platforms:

• Vulkan
• DX12

This is a native only feature.

pub const MULTI_DRAW_INDIRECT: FeaturesWGPU = _

Allows the user to call RenderPass::multi_draw_indirect and RenderPass::multi_draw_indexed_indirect.

Allows multiple indirect calls to be dispatched from a single buffer.

Natively Supported Platforms:

• DX12
• Vulkan

Emulated Platforms:

• Metal
• OpenGL
• WebGPU

Emulation is preformed by looping over the individual indirect draw calls in the backend. This is still significantly faster than enulating it yourself, as wgpu only does draw call validation once.

pub const MULTI_DRAW_INDIRECT_COUNT: FeaturesWGPU = _

Allows the user to call RenderPass::multi_draw_indirect_count and RenderPass::multi_draw_indexed_indirect_count.

This allows the use of a buffer containing the actual number of draw calls.

Supported platforms:

• DX12
• Vulkan 1.2+ (or VK_KHR_draw_indirect_count)

This is a native only feature.

pub const PUSH_CONSTANTS: FeaturesWGPU = _

Allows the use of push constants: small, fast bits of memory that can be updated inside a RenderPass.

Allows the user to call RenderPass::set_push_constants, provide a non-empty array to PipelineLayoutDescriptor, and provide a non-zero limit to Limits::max_push_constant_size.

A block of push constants can be declared in WGSL with var<push_constant>:

struct PushConstants { example: f32, }
var<push_constant> c: PushConstants;

In GLSL, this corresponds to layout(push_constant) uniform Name {..}.

Supported platforms:

• DX12
• Vulkan
• Metal
• OpenGL (emulated with uniforms)

This is a native only feature.

pub const ADDRESS_MODE_CLAMP_TO_ZERO: FeaturesWGPU = _
