Firefox's WebGPU implementation has the following layers: | |||
* Content-visible WebIDL bindings, generated in the usual way from [https://searchfox.org/mozilla-central/source/dom/webidl/WebGPU.webidl <code>dom/webidl/WebGPU.webidl</code>]. | |||
* C++ implementations of those bindings in [https://searchfox.org/mozilla-central/source/dom/webgpu <code>dom/webgpu</code>], which are mostly concerned with marshaling content requests to be sent to the GPU process. | |||
* The [https://searchfox.org/mozilla-central/source/dom/webgpu/ipc/PWebGPU.ipdl <code>PWebGPU</code> IPDL protocol], which carries those requests. | |||
* Rust code in [https://searchfox.org/mozilla-central/source/gfx/wgpu_bindings <code>gfx/wgpu_bindings</code>] to adapt our <code>PWebGPU</code> handlers to call <code>wgpu_core</code> methods. | |||
* The [https://github.com/gfx-rs/wgpu/ <code>wgpu</code>] GitHub project, an independent open source project implementing the core of the WebGPU API in Rust. | |||
* The [https://github.com/gfx-rs/naga/ Naga] GitHub project, which translates WebGPU's shading language into platform API shading languages like SPIR-V, HLSL, and Metal Shading Language. This is used internally by <code>wgpu</code>. | |||
