Solution to Rust errors of kinds:

implementation of Fn is not general enough (works with FnMut and FnOnce as well)
lifetime may not live long enough

use std::future::Future;

trait Callback<Arg, Res> {
    type Output: Future<Output = Res>;

Introduction

This tutorial covers using NetworkManager with either wpa_supplicant or IWD backend. If you did not heard of IWD, it is propbable your NetworkManager uses wpa_supplicant.

UW authorization server uses DSK-NET CA certificate that is self-signed, so we need to specify it manually.

wpa_supplicant

Download the DSK-NET CA certificate:

curl https://it.uw.edu.pl/pl/uslugi/UslugiInternetWiFiEduroam/dsk_net_ca.crt | sudo tee /etc/dsk_net_ca.crt

Before rebooting after making fresh Arch installation

make sure to install grub using grub-install and configure it properly using grub-mkconfig -o /boot/grub/grub.cfg (for uefi it is not so easy), but before running grub-mkconfig install intel-ucode or amd-ucode
install networkmanager vim htop net-tools wireless_tools # net-tools for ifconfig, wireless_tools for iwconfig
remember to configure pacman mirrors properly see /etc/pacman.d/mirrorlist
reboot

On a fresh Arch installation

systemctl enable --now NetworkManager
use nmtui to connect to internet
install git man-pages procps-ng # procps-ng for pkill
