Crash Report

Hello, below you will see the crash report I got when running netscanner on Arch Linux. This does seem to be a ratatui issue though from the the location I was given.

This is a bug. Consider reporting it at https://github.com/Chleba/netscanner

Hi, This is my "widget" for signals. Thank You for this report. I assume that this signal strength for that WiFi network is very good, right? So that visualization will fail to draw because something is out of index.

[DominicOrsi]

Yes, WiFi signal is really good, as in right next to the router good.

[Chleba]

btw. @DominicOrsi - You may be right. Looking at the ratatui code, truncating line (I guess that window where netscanner is running is pretty small) have some issues with span content filled with unicode chars.

[Chleba]

Got it. It looks like my WiFi signal strength limit was badly set. I didn't count with a better signal value than -30. So here's the fix for that: https://github.com/Chleba/netscanner/commit/8db619c4bb566c5a3b1364493ccdada21ce977b2 Please wait for the next version v0.4.5, but I am in the middle of implementing the next big feature (open ports scanning), which I would like to put into it along with this fix. If You would try to build it from the source and give it a try, just let me know if that fixes it for You and go ahead and close this issue. It would be much appreciated. Thanks

[DominicOrsi]

I built from source and all seems to be working well. Thanks for fixing it so fast!
