Classes
class	donner::geode::GeodeWgpuAdapterDevice
	Implements donner::gpu::Device on top of the wgpu device a GeodeDevice already owns, so Geode subsystems can migrate onto the Donner GPU runtime one at a time while the process still renders through wgpu underneath. More...
struct	donner::geode::GeodeWgpuAdapterDevice::MappingSlot::Completion

Namespaces
namespace	donner
	Top-level Donner namespace, which is split into different sub-namespaces such as donner::svg and donner::css.

Functions
gpu::TextureFormat	donner::geode::GpuTextureFormatFromWgpu (wgpu::TextureFormat format)
	Maps a wgpu render-target format onto the donner::gpu format enum.
gpu::TextureUsage	donner::geode::GpuTextureUsageFromWgpu (wgpu::TextureUsage usage)
	Maps wgpu texture usage flags onto the donner::gpu usage flags.

Detailed Description

donner::geode::GeodeWgpuAdapterDevice - the wgpu-backed donner::gpu::Device adapter.

TEMPORARY transition adapter. It is deleted per-platform as each native backend takes over production rendering, and each escape hatch below is deleted with the change that migrates its last caller.

Function Documentation

GpuTextureFormatFromWgpu()

gpu::TextureFormat donner::geode::GpuTextureFormatFromWgpu

(

wgpu::TextureFormat

format

)

Maps a wgpu render-target format onto the donner::gpu format enum.

Halts (release assert) on formats outside the runtime's supported set - RGBA8Unorm, BGRA8Unorm, R8Unorm - which are the only formats Geode's shaders and render targets are built for.

Parameters

format

wgpu texture format to map.

GpuTextureUsageFromWgpu()

gpu::TextureUsage donner::geode::GpuTextureUsageFromWgpu

(

wgpu::TextureUsage

usage

)

Maps wgpu texture usage flags onto the donner::gpu usage flags.

Flags with no runtime equivalent are dropped, so the result describes exactly the capabilities the runtime can express for the texture.

Parameters

usage

wgpu usage flags to map.
