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.

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

Surface Alpha and PresentModes

Surface supports alpha_mode now. When alpha_mode is equal to PreMultiplied or PostMultiplied,
the alpha channel of framebuffer is respected in the compositing process, but which mode is available depends on
the different API and Device. If don't care about alpha_mode, you can set it to Auto.

SurfaceConfiguration {
// ...
+ alpha_mode: surface.get_supported_alpha_modes(&adapter)[0],
}

The function to enumerate supported presentation modes changed:

- pub fn wgpu::Surface::get_supported_modes(&self, adapter: &wgpu::Adapter) -> Vec<PresentMode>
+ pub fn wgpu::Surface::get_supported_present_modes(&self, adapter: &wgpu::Adapter) -> Vec<PresentMode>

Updated raw-window-handle to 0.5

This will allow use of the latest version of winit. As such the bound on create_surface is now RWH 0.5 and requires
both raw_window_handle::HasRawWindowHandle and raw_window_handle::HasRawDisplayHandle.

Bug Fixes

  • Allow running get_texture_format_features on unsupported texture formats (returning no flags) by @cwfitzgerald in #2856
  • Allow multi-sampled textures that are supported by the device but not WebGPU if TEXTURE_ADAPTER_SPECIFIC_FORMAT_FEATURES is enabled by @cwfitzgerald in #2856

v0.13.0

This release includes wgpu, wgpu-core, wgpu-hal, and wgpu-types.

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:

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

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

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

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

- 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.

- 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.

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 CommandEncoders.

Features::WRITE_TIMESTAMP_INSIDE_PASSES is needed to call write_timestamp on RenderPassEncoders or ComputePassEncoders.

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.

- 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:

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

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

FragmentState {
-  targets: &[color_target_state]
+  targets: &[Some(color_target_state)]
  // ..
}
RenderPassDescriptor {
-  color_attachments: &[render_pass_color_attachment]
+  color_attachments: &[Some(render_pass_color_attachment)]
  // ..
}
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:

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 (not an issue if you don't define limits manually):

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

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

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