714: Track buffers and textures in the future submissions r=cwfitzgerald a=kvark **Connections** Fixes https://github.com/gfx-rs/wgpu-rs/issues/362 **Description** When we do `write_buffer` or have it mapped on creation, we record the copy command in a "pending command buffer", which is only actually executed on the next submission. We adjust the submission index on the buffer accordingly. If the buffer is dropped *before* the next submission, and there happens to be a `maintain()` step, there is code that checks if the buffer-associated submission is one of the currently executing ones. If it doesn't fine an active one, it considers the last-used submission to already be done with, which is precisely what is not happening here, since the submission hasn't been scheduled yet. The solution here is to always defer suspecting buffers and textures for deletion till the next submission. The buffers and textures are the only objects that may have "future" submission index, due to `write_buffer` and `write_texture`. **Testing** Confirmed on Linux.

This is an active GitHub mirror of the WebGPU implementation in Rust, which now lives in "gfx/wgpu" of Mozilla-central. Issues and pull requests are accepted, but some bidirectional synchronization may be involved.
WebGPU
This is the core logic of an experimental WebGPU implementation. It's written in Rust and is based on gfx-hal with help of gfx-extras. See the upstream WebGPU specification (work in progress).
The implementation consists of the following parts:
- internal Rust API for WebGPU implementations to use
- Rust types shared between wgpu-core,wgpu-native, andwgpu-rsplayer- standalone application for replaying the API traces, useswinit
This repository contains the core of wgpu, and is not usable directly by applications.
If you are looking for the user-facing Rust API, you need wgpu-rs.
If you are looking for the native implementation or bindings to the API in other languages, you need wgpu-native.
