Trait Implementations

impl AsBindGroup for PositionExtension

type Data = ()

Data that will be stored alongside the “prepared” bind group.

type Param = (Res<'static, RenderAssets<GpuImage>>, Res<'static, FallbackImage>, Res<'static, RenderAssets<GpuShaderStorageBuffer>>)

fn label() -> Option<&'static str>

label

fn unprepared_bind_group( &self, layout: &BindGroupLayout, render_device: &RenderDevice, (images, fallback_image, storage_buffers): &mut SystemParamItem<'_, '_, Self::Param>, force_no_bindless: bool, ) -> Result<UnpreparedBindGroup, AsBindGroupError>

Returns a vec of (binding index, OwnedBindingResource).

fn bind_group_data(&self) -> Self::Data

fn bind_group_layout_entries( render_device: &RenderDevice, force_no_bindless: bool, ) -> Vec<BindGroupLayoutEntry>

Returns a vec of bind group layout entries.

fn bindless_descriptor() -> Option<BindlessDescriptor>

fn bindless_slot_count() -> Option<BindlessSlabResourceLimit>

The number of slots per bind group, if bindless mode is enabled.

fn bindless_supported(_: &RenderDevice) -> bool

True if the hardware actually supports bindless textures for this type, taking the device and driver capabilities into account.

fn as_bind_group( &self, layout: &BindGroupLayout, render_device: &RenderDevice, param: &mut <Self::Param as SystemParam>::Item<'_, '_>, ) -> Result<PreparedBindGroup, AsBindGroupError>

Creates a bind group for self matching the layout defined in AsBindGroup::bind_group_layout.

fn bind_group_layout(render_device: &RenderDevice) -> BindGroupLayout

where Self: Sized,

Creates the bind group layout matching all bind groups returned by AsBindGroup::as_bind_group

impl Asset for PositionExtension

impl Clone for PositionExtension

fn clone(&self) -> PositionExtension

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PositionExtension

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PositionExtension

fn default() -> PositionExtension

Returns the “default value” for a type.

impl MaterialExtension for PositionExtension

fn fragment_shader() -> ShaderRef

Returns this material’s fragment shader. If ShaderRef::Default is returned, the base material mesh fragment shader will be used.

fn vertex_shader() -> ShaderRef

Returns this material’s vertex shader. If ShaderRef::Default is returned, the base material mesh vertex shader will be used.

fn alpha_mode() -> Option<AlphaMode>

fn prepass_vertex_shader() -> ShaderRef

Returns this material’s prepass vertex shader. If ShaderRef::Default is returned, the base material prepass vertex shader will be used.

fn prepass_fragment_shader() -> ShaderRef

Returns this material’s prepass fragment shader. If ShaderRef::Default is returned, the base material prepass fragment shader will be used.

fn deferred_vertex_shader() -> ShaderRef

Returns this material’s deferred vertex shader. If ShaderRef::Default is returned, the base material deferred vertex shader will be used.

fn deferred_fragment_shader() -> ShaderRef

Returns this material’s prepass fragment shader. If ShaderRef::Default is returned, the base material deferred fragment shader will be used.

fn specialize( pipeline: &MaterialExtensionPipeline, descriptor: &mut RenderPipelineDescriptor, layout: &MeshVertexBufferLayoutRef, key: MaterialExtensionKey<Self>, ) -> Result<(), SpecializedMeshPipelineError>

Customizes the default RenderPipelineDescriptor for a specific entity using the entity’s MaterialPipelineKey and MeshVertexBufferLayoutRef as input. Specialization for the base material is applied before this function is called.

impl TypePath for PositionExtension

fn type_path() -> &'static str

Returns the fully qualified path of the underlying type.

fn short_type_path() -> &'static str

Returns a short, pretty-print enabled path to the type.

fn type_ident() -> Option<&'static str>

Returns the name of the type, or None if it is anonymous.

fn crate_name() -> Option<&'static str>

Returns the name of the crate the type is in, or None if it is anonymous.

fn module_path() -> Option<&'static str>

Returns the path to the module the type is in, or None if it is anonymous.
