Data Structures
struct	digital_rain_column_t
	digital rain column keeps the values that move through the subsystem: time_offset, speed_multiplier, phase_offset. Some members are pointers into caller- or subsystem-owned memory, so lifetime follows the API that populated them rather than the struct copy itself. More...
struct	digital_rain
	Digital rain effect context. More...
