# Objective
Calling `RenderDevice::poll` requires an instance of `wgpu::Maintain`,
but the type was not reexported by bevy. Working around it requires
adding a dependency on `wgpu`, since bevy does not reexport the `wgpu`
crate as a whole anywhere.
## Solution
Reexport `wgpu::Maintain` in `render_resource`, where the other wgpu
types are reexported.
