Usage

# build the "release" build of the program
cargo build --release
# put the "release" build somewhere to be used by swaybar
cp ./target/release/swaybar_info ~/.config/sway/

# Alternatively, get it from crates.io/
cargo install swaybar_info
# The `swaybar_info` binary should be placed in $HOME/.cargo/bin/

Put the following in your ~/.config/sway/config (assuming the binary is at $HOME/.config/sway/swaybar_info):

bar {
    position top
    # Set --netdev=<device> such that <device> is the network device you
    # want to monitor. You can omit --netdev=<device>, but that will also
    # cause the program to omit network traffic stats.
    status_command $HOME/.config/sway/swaybar_info --netdev=enp7s0

    # A "built-in" for "acpi -b" is available, and can be activated with the
    # --acpi-builtin flag:

    #status_command $HOME/.config/sway/swaybar_info --acpi-builtin

    # One can use the "--regex-cmd=<cmd>[SPLIT]<args...>[SPLIT]<regex>" option like so:

    #status_command $HOME/.config/sway/swaybar_info --regex-cmd="acpi[SPLIT]-b[SPLIT][0-9]+%.*"

    # This example gets battery info into the bar.
    # Multiple args should be separated with "[SPLIT]".
    # Note that the <args...> portion is optional.


    # The following uses 24 hour time
    #status_command $HOME/.config/sway/swaybar_info --time-format="%Y-%m-%d %R:%S"
}
