what a device can do beyond the Basis level

Fields

timestamps: bool

GPU timestamps on the queue (Timestamps)

multi_draw_indirect: bool

draw_indexed_indirect_multi (several draws from one buffer)

draw_indirect_first_instance: bool

a first instance other than 0 in indirect draws

draw_indirect_count: bool

draw_indexed_indirect_count

bindless: bool

Bindless tables (descriptor indexing, update after bind)

subgroups: bool

subgroup operations (basic, vote, ballot, arithmetic, shuffle) in compute shaders

subgroups_webgpu: bool

what WebGPU’s subgroups feature needs (lib/wgsl’s enable subgroups): the operations of subgroups plus relative shuffles and quad operations, in compute and fragment shaders

subgroup_stages: u32

the stages with subgroup operations (subgroup_stage::) and the operations (subgroup_op::), as the device reports them

subgroup_ops: u32

subgroup_size_control: bool

Device::create_compute_pipeline_sized: a required subgroup size (WGSL @subgroup_size; Limits::subgroup_min_size ..= subgroup_max_size)

subgroup_extended_types: bool

subgroup operations on f16 values too

draw_parameters: bool

the base vertex / base instance / draw index builtins

shader_f16: bool

shader_f64: bool

shader_i16: bool

shader_i64: bool

shader_i8: bool

storage_16bit: bool

16 / 8 bit values in storage buffers

uniform_16bit: bool

16-bit values in uniform buffers and push constants too (WGSL f16 there)

push_constant_16bit: bool

uniform_standard_layout: bool

uniform buffers in the storage layout (uniformBufferStandardLayout: a WGSL uniform buffer whose layout is not std140, e.g. mat2x2f)

demote: bool

OpDemoteToHelperInvocation (lib/wgsl’s discard at the level Voll)

clip_distances: bool

WGSL @builtin(clip_distances), @builtin(primitive_index) (geometryShader), @interpolate(.., sample) / @builtin(sample_index) (sampleRateShading)

primitive_index: bool

sample_shading: bool

storage_8bit: bool

texture_bc: bool

BC1 .. BC7 compressed textures

anisotropy: bool

depth_clamp: bool

vertex_stores: bool

storage writes in vertex / fragment shaders

fragment_stores: bool

storage_write_without_format: bool

storage textures without a format in the shader

buffer_address: bool

shader access to buffers by address

swapchain: bool

presentation to windows (Swapchain)

mesh_shader: bool

present on the adapter, not enabled yet: mesh shaders, ray queries, ray-tracing pipelines

ray_query: bool

ray_pipeline: bool

Trait Implementations

impl Clone for Features

fn clone(&self) -> Self

impl Default for Features

fn default() -> Self

Returns the “default value” for a type.
