Struct GpuFeatures 

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

GPU features that can be requested or required.

These map to common wgpu features that are useful for rendering applications. Use GpuFeatures::to_wgpu() to convert to wgpu::Features.

Implementations

impl GpuFeatures

pub const INDIRECT_FIRST_INSTANCE: Self

Allows the use of first_instance parameter in indirect draw calls. Required for GPU-driven rendering with indirect buffers.

pub const MULTI_DRAW_INDIRECT_COUNT: Self

Allows multi_draw_indirect_count for GPU-driven draw count. In wgpu 27+, multi_draw_indirect() requires no feature flag (only DownlevelFlags::INDIRECT_EXECUTION), but the count variant (multi_draw_indirect_count) requires this feature.

pub const PUSH_CONSTANTS: Self

Allows push constants in shaders for small, frequently updated data. More efficient than uniform buffers for small amounts of per-draw data.

pub const TEXTURE_COMPRESSION_BC: Self

BC texture compression (DXT1, DXT3, DXT5). Common on desktop platforms, reduces texture memory usage.

pub const DEPTH_CLIP_CONTROL: Self

Allows disabling depth clipping in the rasterizer. Useful for certain shadow mapping techniques.

pub const SHADER_F16: Self

16-bit floating point support in shaders. Can improve performance on some GPUs for certain workloads.

pub const INDIRECT_FIRST_VERTEX: Self

Allows non-zero first_vertex and first_instance in indirect draw calls. Note: This is a subset of INDIRECT_FIRST_INSTANCE on some platforms.

pub const POLYGON_MODE_LINE: Self

Polygon mode: line (wireframe rendering).

pub const POLYGON_MODE_POINT: Self

Polygon mode: point.

pub const CONSERVATIVE_RASTERIZATION: Self

Conservative rasterization for better triangle coverage.

pub const TEXTURE_BINDING_ARRAY: Self

Texture binding arrays (bindless textures). Enables more flexible texture access patterns in shaders.

pub const BUFFER_BINDING_ARRAY: Self

Sampled texture and storage buffer binding arrays.

pub const STORAGE_RESOURCE_BINDING_ARRAY: Self

Storage resource binding arrays with dynamic indexing.

pub const PARTIALLY_BOUND_BINDING_ARRAY: Self

Partially bound binding arrays. Allows leaving some array slots unbound.

pub const FLOAT32_FILTERABLE: Self

32-bit floating point texture filtering.

pub const RG11B10UFLOAT_RENDERABLE: Self

RG11B10 unsigned floating point render target format.

pub const BGRA8UNORM_STORAGE: Self

BGRA8 unorm storage texture support.

pub const TIMESTAMP_QUERY: Self

Timestamp queries for GPU profiling. Allows measuring GPU execution time with high precision. Alone, this only allows timestamp writes on pass definition (via timestamp_writes in render/compute pass descriptors).

pub const TIMESTAMP_QUERY_INSIDE_ENCODERS: Self

Allows timestamp write commands at arbitrary points within command encoders. Implies TIMESTAMP_QUERY is supported. Required by wgpu-profiler for scopes on command encoders.

pub const TIMESTAMP_QUERY_INSIDE_PASSES: Self

Allows timestamp write commands at arbitrary points within render/compute passes. Implies TIMESTAMP_QUERY and TIMESTAMP_QUERY_INSIDE_ENCODERS are supported. Required by wgpu-profiler for scopes on render/compute passes.

pub const SAMPLED_TEXTURE_AND_STORAGE_BUFFER_ARRAY_NON_UNIFORM_INDEXING: Self

Non-uniform indexing of sampled texture and storage buffer binding arrays. Required for dynamic indexing into binding_array<texture_2d<f32>> with values that are not uniform across a draw call (e.g., per-instance texture index).
