bind_push_constant() [2/4]

void MayaFlux::Buffers::FormaBindingsProcessor::bind_push_constant	(	const std::string &	name,
		std::function< float()>	reader,
		uint32_t	offset,
		size_t	size = sizeof(float)
	)

Bind a type-erased reader to a push constant slot.

Used by Bridge, which holds readers as std::function<float()> after type-erasing MappedState<T> at register_element time.

Parameters

name	Logical binding name.
reader	Callable returning the current float value each tick.
offset	Byte offset in the push constant struct.
size	Byte width. Defaults to sizeof(float).
