read_buffer()

void MayaFlux::Buffers::DataReadProcessor::read_buffer	(	std::shared_ptr< VKBuffer >	source,
		size_t	byte_count = 0
	)

Read another VKBuffer, such as a descriptor-bound or instance buffer.

Parameters

source	Buffer to read; retained until the request runs.
byte_count	Bytes to read, or zero for its full allocation, which may exceed the bytes its owner currently fills.
