Wgpu-rs: Status of wasm support

[gzp-crey]

I while back my pet project was working on wasm and on pc as well.
I was focusing on the pc and now I've tried to fix the wasm version. The web.rs backend contains a lot of unimplemented functions. (ex a "simple" create_buffer_with_data panic).

What is the status of it ? Is anyone working on it or I have to put wasm away for a while again ?

Thanks.

It's working great, there is a section in README explaining how to use it: https://github.com/gfx-rs/wgpu-rs#run-examples-on-the-web-wasm32-unknown-unknown

There are important caveats though:

1. Levels of browser support are different between vendors. We have the gecko branch that matches Firefox Nightly support.
2. We only have WebGPU WASM backend, there is no support for WebGL WASM yet.

Edit: also, check out https://gfx-rs.github.io/2020/04/21/wgpu-web.html

I was not clear and did not mentioned I'm using main. Here as I see
create_buffer_with_data calls buffer_get_mapped_range_mut in backend/web.rs and it is unimplemented.
(introduced in https://github.com/gfx-rs/wgpu-rs/commit/63219a5a850da0145352535372dbc64e47e107d4)
Am I missing something ?

Again, if you are interested in the code that can run on the Web target, you need to use the gecko branch, which is behind master.
