## Implementations§

source §

### impl Edges

source

#### pub fn input_edges(&self) -> &[Edge]

Returns all “input edges” (edges going “in”) for this node .

source

#### pub fn output_edges(&self) -> &[Edge]

Returns all “output edges” (edges going “out”) for this node .

source

#### pub fn id(&self) -> NodeId

Returns this node’s id.

source

#### pub(crate) fn add_input_edge( &mut self, edge: Edge ) -> Result<(), RenderGraphError>

Adds an edge to the `input_edges` if it does not already exist.

source

#### pub(crate) fn remove_input_edge( &mut self, edge: Edge ) -> Result<(), RenderGraphError>

Removes an edge from the `input_edges` if it exists.

source

#### pub(crate) fn add_output_edge( &mut self, edge: Edge ) -> Result<(), RenderGraphError>

Adds an edge to the `output_edges` if it does not already exist.

source

#### pub(crate) fn remove_output_edge( &mut self, edge: Edge ) -> Result<(), RenderGraphError>

Removes an edge from the `output_edges` if it exists.

source

#### pub fn has_input_edge(&self, edge: &Edge) -> bool

Checks whether the input edge already exists.

source

#### pub fn has_output_edge(&self, edge: &Edge) -> bool

Checks whether the output edge already exists.

source

#### pub fn get_input_slot_edge( &self, index: usize ) -> Result<&Edge, RenderGraphError>

Searches the `input_edges` for a `Edge::SlotEdge`, which `input_index` matches the `index`;

source

#### pub fn get_output_slot_edge( &self, index: usize ) -> Result<&Edge, RenderGraphError>

Searches the `output_edges` for a `Edge::SlotEdge`, which `output_index` matches the `index`;

§

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

§

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

Convert `Box<dyn Trait>` (where `Trait: Downcast`) to `Box<dyn Any>`. `Box<dyn Any>` can then be further `downcast` into `Box<ConcreteType>` where `ConcreteType` implements `Trait`.
§

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

Convert `Rc<Trait>` (where `Trait: Downcast`) to `Rc<Any>`. `Rc<Any>` can then be further `downcast` into `Rc<ConcreteType>` where `ConcreteType` implements `Trait`.
§

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

Convert `&Trait` (where `Trait: Downcast`) to `&Any`. This is needed since Rust cannot generate `&Any`’s vtable from `&Trait`’s.
§

#### fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert `&mut Trait` (where `Trait: Downcast`) to `&Any`. This is needed since Rust cannot generate `&mut Any`’s vtable from `&mut Trait`’s.
§

### impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

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

Convert `Arc<Trait>` (where `Trait: Downcast`) to `Arc<Any>`. `Arc<Any>` can then be further `downcast` into `Arc<ConcreteType>` where `ConcreteType` implements `Trait`.
