bind_structured_node()

void MayaFlux::Buffers::DescriptorBindingsProcessor::bind_structured_node	(	const std::string &	name,
		const std::shared_ptr< Nodes::Node > &	node,
		const std::string &	descriptor_name,
		uint32_t	set,
		vk::DescriptorType	type = vk::DescriptorType::eStorageBuffer
	)

Bind structured node (arrays of POD structs) to descriptor.

Parameters

name	Logical binding name
node	Node that creates context with GpuStructuredData
descriptor_name	Name in shader config bindings
set	Descriptor set index
type	Typically eStorageBuffer for structured arrays
