702: Fix SwapChainOutput Related Segfault r=kvark a=cwfitzgerald
If a user accidentally recreates a swapchain after grabbing a SwapChainOutput, then renders to it, this will trigger a segfault on render. This can be reproduced by replacing the get_next_frame code in any example with:
```rust
let frame = swap_chain
.get_next_frame()
.expect("Failed to acquire next swap chain texture")
.output;
device.create_swap_chain(&surface, &sc_desc);
```
I have tested the examples, and they still work after this change, and it correctly detects this condition.
Oddly enough the following code does not panic, nor actually raise any errors, even with this PR.
```rust
let tmp = device.create_swap_chain(&surface, &sc_desc);
let frame = swap_chain
.get_next_frame()
.expect("Failed to acquire next swap chain texture")
.output;
swap_chain = tmp;
```
I'm not entirely sure why.

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.
