## Unreleased

### Major Changes

#### @invariant Warning

When using CompareFunction::Equal or CompareFunction::NotEqual on a pipeline, there is now a warning logged if the vertex
shader does not have a @invariant tag on it. On some machines, rendering the same triangles multiple times without an
@invariant tag will result in slightly different depths for every pixel. Because the *Equal functions rely on depth being
the same every time it is rendered, we now warn if it is missing.

```diff
-@vertex 
-fn vert_main(v_in: VertexInput) -> @builtin(position) vec4<f32> {...}
+@vertex 
+fn vert_main(v_in: VertexInput) -> @builtin(position) @invariant vec4<f32> {...}
```

## wgpu-0.13 (2022-06-30)

### Major Changes

#### WGSL Syntax

WGSL syntax has changed in a couple ways. The new syntax is easier to read and work with.

Attribute declarations are written differently:

```diff
- [[group(1), binding(0)]]
+ @group(1) @binding(0)
```

Stage declarations are now separate attributes rather than part of the `stage` attribute:

```diff
- [[stage(vertex)]]
+ @vertex
```

Structs now use `,` as field separator and no longer need semicolons after the declaration:

```diff
- struct MyStruct {
-     my_member: u32;
- };
+ struct MyStruct {
+     my_member: u32,
+ }
```

#### Surface API

The method of getting the preferred swapchain format has changed to allow viewing all formats supported by the surface.

```diff
- let format = surface.get_preferred_format(&adapter).unwrap();
+ let format = surface.get_supported_formats(&adapter)[0];
```

Presentation modes now need to match exactly what the surface supports. `FIFO` is _always_ supported,
but all other modes vary from API to API and `Device` to `Device`. To get a list of all supported modes,
call the following. The order does not indicate preference.

```rust
let modes = surface.get_supported_present_modes(&adapter);
```

#### Timestamp Queries

Timestamp queries are now restricted behind multiple features to allow implementation on TBDR (Tile-Based Deferred Rendering)
based GPUs, such as mobile devices and Apple's M chips.

`Features::TIMESTAMP_QUERIES` now allows for calling `write_timestamp` only on `CommandEncoder`s.

`Features::WRITE_TIMESTAMP_INSIDE_PASSES` is needed to call `write_timestamp` on `RenderPassEncoder`s or `ComputePassEncoder`s.

#### map_async

The function for mapping buffers no longer returns a future, and instead calls a callback when the buffer is mapped.

This aligns with the use of the API more clearly - you aren't supposed to block and wait on the future to resolve,
you are supposed to keep rendering and wait until the buffer maps on its own. Mapping and the flow of mapping
is an under-documented area that we hope to improve in the future.

```diff
- let future = buffer.slice(..).map_async(MapMode::Read);
+ buffer.slice(..).map_async(MapMode::Read, || {
+     // Called when buffer is mapped.
+ })
```

#### Submission Indexes

Calling `queue.submit` now returns an opaque submission index that can be used as an argument to
`device.poll` to say which submission to wait to complete.

### Other Breaking Changes

`Device::create_shader_module` now takes the shader descriptor by value:

```diff
- device.create_shader_module(&shader_module_descriptor)
+ device.create_shader_module(shader_module_descriptor)
```

Color attachments can be sparse, so they are now optional:

```diff
FragmentState {
-  targets: &[color_target_state]
+  targets: &[Some(color_target_state)]
  // ..
}
```

```diff
RenderPassDescriptor {
-  color_attachments: &[render_pass_color_attachment]
+  color_attachments: &[Some(render_pass_color_attachment)]
  // ..
}
```

```diff
RenderBundleEncoderDescriptor {
-  color_formats: &[texture_format]
+  color_formats: &[Some(texture_format)]
  // ..
}
```

`Extent3d::max_mips` now requires you to pass a TextureDimension to specify whether or not depth_or_array_layers should be ignored:

```diff
Extent3d {
  width: 1920,
  height: 1080,
  depth_or_array_layers: 6,
- }.max_mips()
+ }.max_mips(wgpu::TextureDimension::D3)
```

`Limits` has a new field, [`max_buffer_size`](https://docs.rs/wgpu/0.13.0/wgpu/struct.Limits.html#structfield.max_buffer_size) (not an issue if you don't define limits manually):

```diff
Limits {
  // ...
+ max_buffer_size: 256 * 1024 * 1024, // adjust as you see fit
}
```

`Features::CLEAR_COMMANDS` is now unnecessary and no longer exists. The feature to clear buffers and textures is now part of upstream WebGPU.

```diff
DeviceDescriptor {
  // ...
  features: wgpu::Features::VERTEX_WRITABLE_STORAGE
    | wgpu::Features::MAPPABLE_PRIMARY_BUFFERS
    | wgpu::Features::TEXTURE_BINDING_ARRAY
    | wgpu::Features::BUFFER_BINDING_ARRAY
    | wgpu::Features::STORAGE_RESOURCE_BINDING_ARRAY
-    | wgpu::Features::CLEAR_COMMANDS
  ,
}
```

`ComputePass::dispatch` has been renamed to `ComputePass::dispatch_workgroups`

```diff
- cpass.dispatch(self.work_group_count, 1, 1)
+ cpass.dispatch_workgroups(self.work_group_count, 1, 1)
```

  - processing SPIR-V inputs for later translation now requires `spirv` compile feature enabled
  - new `Features::SPIRV_SHADER_PASSTHROUGH` run-time feature allows providing pass-through SPIR-V (orthogonal to the compile feature)
  - several bitflag names are renamed to plural: `TextureUsage`, `BufferUsage`, `ColorWrite`.
  - the `SwapChain` is merged into `Surface`. Returned frames are `Texture` instead of `TextureView`.
  - renamed `TextureUsage` bits: `SAMPLED` -> `TEXTURE_BINDING`, `STORAGE` -> `STORAGE_BINDING`.
  - renamed `InputStepMode` to `VertexStepMode`.
  - readable storage textures are no longer a part of the base API. Only exposed via format-specific features, non-portably.
  - implemented `Rgb9e5Ufloat` format.

  - reworked downlevel flags, added downlevel limits.
  - `resolver = "2"` is now required in top-level cargo manifests
- Fixed:
  - `Device::create_query_set` would return an error when creating exactly `QUERY_SET_MAX_QUERIES` (8192) queries. Now it only returns an error when trying to create _more_ than `QUERY_SET_MAX_QUERIES` queries.
