newtype DriverState h r s f z g p i o eff

The type used to track a driver's persistent state.

• h is the type of value the components produce for rendering.
• r is the type for the render state for the driver.
• s is the component state type.
• f is the projected component query algebra - used for multi-child-type components, by projecting to z we can avoid the need to remap the entire component.
• z is the unprojected component query algebra.
• g is the component child query algebra.
• p is the type of slots for the component.
• i is the invput value type.
• o is the type of output messages from the component.
• eff is the effect row for the target Aff
