write_layer() [1/2]

void MayaFlux::Kriya::detail::write_layer	(	const std::shared_ptr< Buffers::VKBuffer > &	target,
		uint32_t	layer,
		const Kakshya::DataVariant &	data
	)

Write a DataVariant into one layer of a layered buffer.

An empty variant is skipped, as when nothing has arrived yet. The bytes must match the layer's size, which the buffer reports when they do not.

Parameters

target	Buffer that passed accepts_layer_write.
layer	Layer to replace.
data	Frame bytes.
