In order to obtain the RX and TX bitrates from the kernel netlink we need to open a second info socket to get the station data. The values are formatted like "1.9Gb/s" and then exposed as `rx_bitrate` and `tx_bitrate`.
This code is closely following the `iw` implementation.
When an interface is not specified for the network module, we parse the
routing table to look for default routes.
We have defined a default route to:
- have a gateway specified, and
- have no destination specified, or have an all-zero destination.
Previous versions of Waybar had the second condition inverted,
causing it to incorrectly pick interfaces are used to route a
subnet/single host.
For example, with the following routing table, we should pick `eth0` to
show information about, not `wg0`.
```
ip -4 route
default via 192.168.252.1 dev eth0 proto dhcp src 192.168.252.200 metric 100
192.168.252.0/24 dev eth0 proto kernel scope link src 192.168.252.200 metric 100
192.168.2.254 via 192.168.1.1 dev wg0 proto static metric 50
192.168.1.0/24 dev wg0 proto static scope link metric 50
192.168.1.0/24 dev wg0 proto kernel scope link src 192.168.1.254 metric 50
```
- Replaced pass-by-value std::string parameters with const std::string&
or std::string_view to prevent SSO overallocations.
- Refactored static mapping functions in UPower to return
std::string_view instead of constructing std::string literals, enabling
perfect cache locality.
- Optimized string concatenation in hot loops (network IPs, inhibitor
lists, sway window marks) by using std::string::append() and
pre-reserving capacity instead of overloaded operator+ which produces
temporary heap instances.
These optimizations reduce high-frequency memory churn and overall heap
fragmentation within the main rendering loops.

I'm not sure why, but my network card (mt7921e) sometimes will report
having a carrier when the interface is down. This usually happens
when rfkill was active before rebooting.
This setting makes it possible to have a configuration with two
network modules where one of them displays the ethernet state
(disconnected, linked, ethernet), and the other, the wifi state
(disabled, disconnected, linked, wifi).
Otherwise the ethernet state would show up as "disabled" (instead of
"disconnected") when rfkill is active.
There were two main issues with fmtlib and C++20 mode:
- `fmt::format` defaults to compile-time argument checking and requires
using `fmt::runtime(format_string)` to bypass that.
- `std::format` implementation introduces conflicting declarations and
we have to specify the namespace for all `format`/`format_to` calls.
Mouse-over tooltips set on the label only appear once the mouse hovers
over exactly the label. Other apps (e.g. firefox) show the tooltip once
the pointer hovers the button. Not solely its label. With this commit we
get the same behaviour.
Fixes issue where the class parameters in style.css would have no
effect.
The CSS now references the GtkButton instead of the GtkLabel. Removing
all style-classes from the custom module GtkButton however removes
any properties set via style.css. Thus, the default classes 'flat' and
'text-button' are added on every update of these modules.
The AButton class is designed as full a substitute to ALabel. The
GtkButton attribute 'button_' is initialized with a label. This
label can the be referenced by the subsequent inheritors of AButton
instead of the GtkLabel attribute 'label_' of ALabel.
For convenience a GtkLabel* 'label_' attribute is added to AButton.
If the button cannot be clicked it is disabled, effectively acting
like its label predecessor.
GtkButton seems to catch one-click mouse events regardless of the
flags set on it. Therefore, 'signal_pressed' is connected to a
function creating a fake GdkEventButton* and calling 'handleToggle'
(for details on this possible bug in GTK see:
https://stackoverflow.com/questions/45334911 )
In accordance with other GtkButtons (i.e. the sway/workspace ones)
set_relief(Gtk::RELIEF_NONE) is called on the 'button_' instance.
