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_env
  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_list
  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
