Texture format R8Unorm | R16Float not supported for storage use.

[jinleili]

I'm trying to convert my project's glsl to wgsl on macOS,
the shader works fine when this project uses wgpu-rs v0.5, but now encountered a validation error:

 wgpu error: Validation Error

Caused by:
    In Device::create_compute_pipeline
    error matching global ResourceBinding { group: 0, binding: 5 } against the pipeline layout
    texture format R16Float is not supported for storage use

original glsl shader:

layout(local_size_x = 16, local_size_y = 16) in;
...
layout(binding = 5, r16f) uniform readonly image2D input_pic;
layout(binding = 6, r16f) uniform writeonly image2D output_pic;

void main() {
    ...
}

wgsl shader:

...
[[group(0), binding(5)]] var input_pic: [[access(read)]] texture_storage_2d<r16float>;
[[group(0), binding(6)]] var output_pic: [[access(write)]] texture_storage_2d<r16float>;

[[stage(compute), workgroup_size(16, 16)]]
fn main([[builtin(global_invocation_id)]] GlobalInvocationID: vec3<u32>) {
    ...
}

This is by design. See the table in https://gpuweb.github.io/gpuweb/#plain-color-formats for the baseline capabilities. If you need to opt into native-only non-portable behavior, you can enable TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES feature.
