This is a repo full of explorations into various Rust language features and crates. They are written for didactic exposition where possible. In the future, these can be turned into tutorials on developerlife.com or videos on the developerlife.com YouTube channel

1. timer & service to change GNOME 47 wallpaper on ubuntu

https://github.com/nazmulidris/notes/blob/main/workflow/gist/systemd-service-recurring-change-wallpaper.md

the service and timer files are static in this example.
script
Illustrate the difference between the service and timer.
Provide a fish script that is used to run other scripts. The wisdom of this approach is that multiple scripts can be run in a pipeline w/ no extra effort!
Provide a few scripts to showcase how this works (eg: change wallpaper, set max brightness, any other recurring tasks)

2. service to mount sshfs shares

the service file is created dynamically in this example.
script

Example of using following:

After=network.target
[Service]
User=nazmul
Type=oneshot
RemainAfterExit=yes
Restart=on-failure

provide fish script that generates this

3. replace the use of fish with rust programs to do this!

create this in the rust-scratch repo
migrate the existing fish script(s) to rust. instead of dynamically creating a script using fish, use Rust. do the same for timer file and others as well.
provide the ability to query systemctl to see the service status, and some other niceties from the Rust program. This is a primer that will evolve into the full blown capabilities of r3bl-cmdr and beyond (with applets).
