Struct FlightRecorder 

pub struct FlightRecorder { /* private fields */ }

Keeps the last minutes on screen in memory, the way a flight recorder does, so that a bug can show what led to it. Put it anywhere in the app’s views: it draws nothing. A film costs little because each thing drawn is stored once and a screen that does not change costs nothing, and it runs only when the app paints.

It sees all that the app shows, so it writes nothing anywhere: only Self::film gets anything out of it.

use ravenrs_movie::FlightRecorder;

// The last three minutes.
let recorder = FlightRecorder::new(180.0);
assert!(recorder.film().is_none(), "nothing on screen yet");
