Struct WgpuDispatcher 

pub struct WgpuDispatcher<'a> { /* private fields */ }

Dispatcher that compiles engawa render graphs to wgpu commands. Construct once; call dispatch_graph per frame.

Implementations

impl<'a> WgpuDispatcher<'a>

pub fn new( device: &'a Device, queue: &'a Queue, target_format: TextureFormat, ) -> Self

pub fn dispatch_with( &mut self, graph: &CompiledGraph, bindings: ResourceBindings, bound: BoundResources, ) -> Result<CommandBuffer, WgpuDispatcherError>

One-shot helper: compile (if needed), build bindings, walk the graph, return the recorded CommandBuffer ready to submit. Wraps the trait’s dispatch_graph + encoder lifecycle so the call site stays one line.

Trait Implementations

impl<'a> Dispatcher for WgpuDispatcher<'a>

fn dispatch_node( &mut self, node: &Node, _bindings: &ResourceBindings, ) -> Result<(), DispatchError>

Dispatch a single node. Called by dispatch_graph in execution order. Implementations record / encode / dispatch as appropriate for their backend.

fn dispatch_graph( &mut self, graph: &CompiledGraph, bindings: &ResourceBindings, ) -> Result<(), DispatchError>

Walk graph.execution_order, validating bindings + then calling dispatch_node for each. The default impl handles all engawa-side concerns; backends typically don’t override this.
