Struct PostProcessBindGroupCache

pub struct PostProcessBindGroupCache { /* private fields */ }

Expand description

Caches the bind groups for each main textures used when making a post processing effect

Implementations§

Source §

impl PostProcessBindGroupCache

Source

pub fn new<F>( view_target: &ViewTarget, create_bind_group: F, ) -> PostProcessBindGroupCache
where F: CreatePostProcessBindGroup,

Creates the bind group for both main textures used in post processing effects

Source

pub fn should_update(&self, view_target: &ViewTarget) -> bool

Determines if the bind groups need to be updated based on the main textures id

If you have anything else that determines if the bind groups need to be updated you need to do it manually

Source

pub fn update<F>( &mut self, view_target: &ViewTarget, builder: PostProcessBindGroupCacheBuilder<F>, )
where F: CreatePostProcessBindGroup,

Updates the bind group associated with each main textures

Use the builder to get the callback used when creating the bind group

Source

pub fn get_current_bind_group(&self, texture: &TextureView) -> &BindGroup

Gets the bind group associated with the current main texture

Generally, this will be the bind group associated with the source texture

impl<T, U> AsBindGroupShaderType for T
where U: ShaderType, &'a T: for<'a> Into,

Source §

fn as_bind_group_shader_type(&self, _images: &RenderAssets<GpuImage>) -> U

Return the T ShaderType for self. When used in AsBindGroup derives, it is safe to assume that all images in self exist.

impl<T> Downcast for T
where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

where T: Any + Send + Sync,

Source §

fn into_any_sync(self: Box<T>) -> Box<dyn Any + Send + Sync>

Converts Box<Trait> (where Trait: DowncastSync) to Box<dyn Any + Send + Sync>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.

Source §

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync> ⓘ

Converts Arc<Trait> (where Trait: DowncastSync) to Arc<Any>, which can then be downcast into Arc<ConcreteType> where ConcreteType implements Trait.

where T: ?Sized,

Source §

const TYPE_EQ: TypeEq<T, <T as Identity>::Type> = TypeEq::NEW

Proof that Self is the same type as Self::Type, provides methods for casting between Self and Self::Type.

Source §

type Type = T

The same type as Self, used to emulate type equality bounds (T == U) with associated type equality constraints (T: Identity<Type = U>).
