Module wgpu::util

Utility structures and functions that are built on top of the main wgpu API.

Nothing in this module is a part of the WebGPU API specification; they are unique to the wgpu library.

Structs

BufferInitDescriptor

Describes a Buffer when allocating.

DispatchIndirect

The structure expected in indirect_buffer for ComputePass::dispatch_workgroups_indirect.

DownloadBuffer

CPU accessible buffer used to download data back from the GPU.

DrawIndexedIndirect

The structure expected in indirect_buffer for RenderEncoder::draw_indexed_indirect.

DrawIndirect

The structure expected in indirect_buffer for RenderEncoder::draw_indirect.

StagingBelt

Efficiently performs many buffer writes by sharing and reusing temporary buffers.

Traits

DeviceExt

Utility methods not meant to be in the main API.

RenderEncoder

Methods shared by RenderPass and RenderBundleEncoder.

Functions

align_to

Aligns a value to an alignment.

backend_bits_from_env

Get a set of backend bits from the environment variable WGPU_BACKEND.

dx12_shader_compiler_from_env

Choose which DX12 shader compiler to use from the environment variable WGPU_DX12_COMPILER.

initialize_adapter_from_envNon-WebAssembly

Initialize the adapter obeying the WGPU_ADAPTER_NAME environment variable.

initialize_adapter_from_env_or_default

Initialize the adapter obeying the WGPU_ADAPTER_NAME environment variable and if it doesn’t exist fall back on a default adapter.

make_spirv_raw

Version of make_spirv intended for use with Device::create_shader_module_spirv. Returns raw slice instead of ShaderSource.

parse_backends_from_comma_listNon-WebAssembly or wgc

Generates a set of backends from a comma separated list of case-insensitive backend names.

power_preference_from_env

Get a power preference from the environment variable WGPU_POWER_PREF
