I was trying out the sample and faced a blank screen and was confused. Nothing appeared but a blank screen until I pressed a key (multiple terminals).
It seems the
crossterm::event::read()method is blocking. Its docs recommend usingcrossterm::event::poll(...)to avoid this. I used the recommended 100ms and CPU usage is quite low, as expected.
