This ports my dmi icon state parser from https://github.com/Absolucy/icon-presence-cache - which just directly reads the (quite simple) zTXT header, rather than using the
dmi
crate - which will decode all the image data too, despite the fact we don't need any of that in order to just list the icon states.icon-presence-cache
is capable of parsing the icon states of every single .dmi on tgstation master in 1.8 seconds, while it took 3.5 seconds using thedmi::Icon
approach, so this should be plenty fast.
