Description
ratatui
does a great job of only updating cells that are different between render, but constructing thevt100
screen can be intensive.This PR avoid constructing the screen if there are no updates to the the app state meaning there's no reason to re-render the TUI.
There are some additional changes we can also make to lower CPU usage more:
Screen
is less resource intensive e.g. perf: avoid allocation on Cell::contents doy/vt100-rust#14Testing Instructions
