IceSentry 6d0c11a28f Bind group layout entries (#10224) ... # Objective - Follow up to #9694 ## Solution - Same api as #9694 but adapted for `BindGroupLayoutEntry` - Use the same `ShaderStages` visibilty for all entries by default - Add `BindingType` helper function that mirror the wgsl equivalent and that make writing layouts much simpler. Before: ```rust let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor { label: Some("post_process_bind_group_layout"), entries: &[ BindGroupLayoutEntry { binding: 0, visibility: ShaderStages::FRAGMENT, ty: BindingType::Texture { sample_type: TextureSampleType::Float { filterable: true }, view_dimension: TextureViewDimension::D2, multisampled: false, }, count: None, }, BindGroupLayoutEntry { binding: 1, visibility: ShaderStages::FRAGMENT, ty: BindingType::Sampler(SamplerBindingType::Filtering), count: None, }, BindGroupLayoutEntry { binding: 2, visibility: ShaderStages::FRAGMENT, ty: BindingType::Buffer { ty: bevy::render::render_resource::BufferBindingType::Uniform, has_dynamic_offset: false, min_binding_size: Some(PostProcessSettings::min_size()), }, count: None, }, ], }); ``` After: ```rust let layout = render_device.create_bind_group_layout( "post_process_bind_group_layout"), &BindGroupLayoutEntries::sequential( ShaderStages::FRAGMENT, ( texture_2d_f32(), sampler(SamplerBindingType::Filtering), uniform_buffer(false, Some(PostProcessSettings::min_size())), ), ), ); ``` Here's a more extreme example in bevy_solari: 86dab7f5da --- ## Changelog - Added `BindGroupLayoutEntries` and all `BindingType` helper functions. ## Migration Guide `RenderDevice::create_bind_group_layout()` doesn't take a `BindGroupLayoutDescriptor` anymore. You need to provide the parameters separately ```rust // 0.12 let layout = render_device.create_bind_group_layout(&BindGroupLayoutDescriptor { label: Some("post_process_bind_group_layout"), entries: &[ BindGroupLayoutEntry { // ... }, ], }); // 0.13 let layout = render_device.create_bind_group_layout( "post_process_bind_group_layout", &[ BindGroupLayoutEntry { // ... }, ], ); ``` ## TODO - [x] implement a `Dynamic` variant - [x] update the `RenderDevice::create_bind_group_layout()` api to match the one from `RenderDevice::creat_bind_group()` - [x] docs		2023-11-28 04:00:49 +00:00
