Description
The WebGPU specification includes:

depthSlice, of type GPUIntegerCoordinate

Indicates the depth slice index of "3d" view that will be output to for this color attachment.

But wgpu::RenderPassColorAttachment has no such field. Either this is a missing feature, or there is an intentional API deviation that is not documented and should be.

Platform
wgpu 0.18.0
