Struct screen_13::graph::Resolver

pub struct Resolver<P> where
    P: SharedPointerKind,  { /* private fields */ }

A structure which can read and execute render graphs. This pattern was derived from:

Implementations

impl<P> Resolver<P> where
    P: SharedPointerKind, 

pub fn node_stage_mask(&self, node: impl Node<P>) -> PipelineStageFlags

Returns the stages that process the given node.

Note that this value must be retrieved before resolving a node as there will be no data left to inspect afterwards!

pub fn record_node_dependencies(
    &mut self,
    cache: &mut HashPool<P>,
    cmd_buf: &CommandBuffer<P>,
    node: impl Node<P>
) -> Result<(), DriverError> where
    P: 'static, 

Records any pending render graph passes that are required by the given node, but does not record any passes that actually contain the given node.

As a side effect, the graph is optimized for the given node. Future calls may further optimize the graph, but only on top of the existing optimizations. This only matters if you are pulling multiple images out and you care - in that case pull the “most important” image first.

pub fn record_node(
    &mut self,
    cache: &mut HashPool<P>,
    cmd_buf: &CommandBuffer<P>,
    node: impl Node<P>
) -> Result<(), DriverError> where
    P: 'static, 

Records any pending render graph passes that the given node requires.

pub fn unbind_node<N>(&mut self, node: N) -> <N as Edge<Self>>::Result where
    N: Edge<Self>,
    N: Unbind<Self, <N as Edge<Self>>::Result>, 

Trait Implementations

impl<P: Debug> Debug for Resolver<P> where
    P: SharedPointerKind, 

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

Formats the value using the given formatter.

impl<P> Unbind<Resolver<P>, SwapchainImage<P>> for SwapchainImageNode<P> where
    P: SharedPointerKind, 

fn unbind(self, graph: &mut Resolver<P>) -> SwapchainImage<P>
