# Objective
- Allow bevy and wgpu developers to test newer versions of wgpu without
having to update naga_oil.
## Solution
- Currently bevy feeds wgsl through naga_oil to get a naga::Module that
it passes to wgpu.
- Added a way to pass wgsl through naga_oil, and then serialize the
naga::Module back into a wgsl string to feed to wgpu, allowing wgpu to
parse it using it's internal version of naga (and not the version of
naga bevy_render/naga_oil is using).
## Testing
1. Run 3d_scene (it works)
2. Run 3d_scene with `--features bevy_render/decoupled_naga` (it still
works)
3. Add the following patch to bevy/Cargo.toml, run cargo update, and
compile again (it will fail)
```toml
[patch.crates-io]
wgpu = { git = "https://github.com/gfx-rs/wgpu", rev = "2764e7a39920e23928d300e8856a672f1952da63" }
wgpu-core = { git = "https://github.com/gfx-rs/wgpu", rev = "2764e7a39920e23928d300e8856a672f1952da63" }
wgpu-hal = { git = "https://github.com/gfx-rs/wgpu", rev = "2764e7a39920e23928d300e8856a672f1952da63" }
wgpu-types = { git = "https://github.com/gfx-rs/wgpu", rev = "2764e7a39920e23928d300e8856a672f1952da63" }
```
4. Fix errors and compile again (it will work, and you didn't have to
touch naga_oil)
