Ich, einfach anders

Thanks for coming back to this!

Nice

That’s just brilliant.

To be fair, these alternatives are also limited to the case where the item type stays the same.

map() can still be used with Vec::iter_mut(), filter_map() can be replaced with Vec::retain_mut().

I think the better solution would be to use Vec::retain().

Tl;dr: std::process::Command is vulnerable to shell injection if you invoke cmd.exe or *.{cmd,bat} on Windows.

Does “cross platform apps” include Windows in your case? If so, how is your experience compiling and packaging a libadwaita app for Windows?
