Struct FeaturesWebGPU 

pub struct FeaturesWebGPU(/* private fields */);

Available on crate feature unstable-wgpu-26 only.

Features that are not guaranteed to be supported.

These are part of the webgpu standard. 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 FeaturesWebGPU

pub const DEPTH_CLIP_CONTROL: FeaturesWebGPU

By default, polygon depth is clipped to 0-1 range before/during rasterization. Anything outside of that range is rejected, and respective fragments are not touched.

With this extension, we can disabling clipping. That allows shadow map occluders to be rendered into a tighter depth range.

Supported platforms:

• desktops
• some mobile chips

This is a web and native feature.

pub const DEPTH32FLOAT_STENCIL8: FeaturesWebGPU

Allows for explicit creation of textures of format TextureFormat::Depth32FloatStencil8

Supported platforms:

• Vulkan (mostly)
• DX12
• Metal
• OpenGL

This is a web and native feature.

pub const TEXTURE_COMPRESSION_BC: FeaturesWebGPU

Enables BCn family of compressed textures. All BCn textures use 4x4 pixel blocks with 8 or 16 bytes per block.

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 BCn formats. Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES may enable additional usages.

This feature guarantees availability of sliced-3d textures for BC formats when combined with TEXTURE_COMPRESSION_BC_SLICED_3D.

Supported Platforms:

• desktops
• Mobile (All Apple9 and some Apple7 and Apple8 devices)

This is a web and native feature.

pub const TEXTURE_COMPRESSION_BC_SLICED_3D: FeaturesWebGPU

Allows the 3d dimension for textures with BC compressed formats.

This feature must be used in combination with TEXTURE_COMPRESSION_BC to enable 3D textures with BC compression. It does not enable the BC formats by itself.

Supported Platforms:

• desktops
• Mobile (All Apple9 and some Apple7 and Apple8 devices)

This is a web and native feature.

pub const TEXTURE_COMPRESSION_ETC2: FeaturesWebGPU

Enables ETC family of compressed textures. All ETC textures use 4x4 pixel blocks. ETC2 RGB and RGBA1 are 8 bytes per block. RTC2 RGBA8 and EAC are 16 bytes per block.

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 ETC2 formats. Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES may enable additional usages.

Supported Platforms:

• Vulkan on Intel
• Mobile (some)

This is a web and native feature.

pub const TEXTURE_COMPRESSION_ASTC: FeaturesWebGPU

Enables ASTC family of compressed textures. ASTC textures use pixel blocks varying from 4x4 to 12x12. Blocks are always 16 bytes.

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 Unorm/UnormSrgb channel type. Features::TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES may enable additional usages.

This feature does not guarantee availability of sliced 3d textures for ASTC formats. If available, 3d support can be enabled by TEXTURE_COMPRESSION_ASTC_SLICED_3D feature.

Supported Platforms:

• Vulkan on Intel
• Mobile (some)

This is a web and native feature.

pub const TEXTURE_COMPRESSION_ASTC_SLICED_3D: FeaturesWebGPU

Allows the 3d dimension for textures with ASTC compressed formats.

This feature must be used in combination with TEXTURE_COMPRESSION_ASTC to enable 3D textures with ASTC compression. It does not enable the ASTC formats by itself.

Supported Platforms:

• Vulkan (some)
• Metal on Apple3+
• OpenGL/WebGL (some)

Not Supported:

• DX12

This is a web and native feature.

pub const TIMESTAMP_QUERY: FeaturesWebGPU

Enables use of Timestamp Queries. These queries tell the current gpu timestamp when all work before the query is finished.

This feature allows the use of

• RenderPassDescriptor::timestamp_writes
• ComputePassDescriptor::timestamp_writes to write out timestamps.

For arbitrary timestamp write commands on encoders refer to Features::TIMESTAMP_QUERY_INSIDE_ENCODERS. For arbitrary timestamp write commands on passes refer to Features::TIMESTAMP_QUERY_INSIDE_PASSES.

They must be resolved using CommandEncoder::resolve_query_set into a buffer, then the result must be multiplied by the timestamp period Queue::get_timestamp_period to get the timestamp in nanoseconds. Multiple timestamps can then be diffed to get the time for operations between them to finish.

Supported Platforms:

• Vulkan
• DX12
• Metal

This is a web and native feature.

pub const INDIRECT_FIRST_INSTANCE: FeaturesWebGPU

Allows non-zero value for the first_instance member in indirect draw calls.

If this feature is not enabled, and the first_instance member is non-zero, the behavior may be:

• The draw call is ignored.
• The draw call is executed as if the first_instance is zero.
• The draw call is executed with the correct first_instance value.

Supported Platforms:

• Vulkan (mostly)
• DX12
• Metal on Apple3+ or Mac1+
• OpenGL (Desktop 4.2+ with ARB_shader_draw_parameters only)

Not Supported:

• OpenGL ES / WebGL

This is a web and native feature.

pub const SHADER_F16: FeaturesWebGPU

Allows shaders to use 16-bit floating point types. You may use them uniform buffers, storage buffers, and local variables. You may not use them in push constants.

In order to use this in WGSL shaders, you must add enable f16; to the top of your shader, before any global items.

Supported Platforms:

• Vulkan
• Metal
• DX12

This is a web and native feature.

• Vulkan (mainly on Desktop GPUs)
• DX12
• Metal on macOS or Apple9+ GPUs, optional on iOS/iPadOS with Apple7/8 GPUs
• GL with one of GL_ARB_color_buffer_float/GL_EXT_color_buffer_float/OES_texture_float_linear

This is a web and native feature.

pub const DUAL_SOURCE_BLENDING: FeaturesWebGPU

Allows two outputs from a shader to be used for blending. Note that dual-source blending doesn’t support multiple render targets.
