## Features

* serde: Enable to make structs in this crate De-/Serializable

## Limitations

Currently SystemD Version <245 are not supported as unit-file-list changed from two column to three column setup. See: [SystemD Changelog](https://github.com/systemd/systemd/blob/16bfb12c8f815a468021b6e20871061d20b50f57/NEWS#L6073)

## Unit / service operation

Nominal service operations:

```rust

let systemctl = systemctl::SystemCtl::default();

systemctl.stop("systemd-journald.service")

    .unwrap();

systemctl.restart("systemd-journald.service")

    .unwrap();

if let Ok(true) = systemctl.exists("ntpd") {

    let is_active = systemctl.is_active("ntpd")

        .unwrap();

}

```

## Service enumeration

```rust

let systemctl = systemctl::SystemCtl::default();

// list all units

systemctl.list_units(None, None, None);

// list all services 

// by adding a --type filter

systemctl.list_units(Some("service"), None, None);

// list all services currently `enabled` 

// by adding a --state filter

systemctl.list_units(Some("service"), Some("enabled"), None);

// list all services starting with cron

systemctl.list_units(Some("service"), None, Some("cron*"));

```

## Unit structure

Use the unit structure for more information

```rust

let systemctl = systemctl::SystemCtl::default();

let unit = systemctl.create_unit("ssh.service")

    .unwrap();

systemctl.restart(&unit.name).unwrap();

println!("active: {}", unit.active);

println!("preset: {}", unit.preset);

if let Some(docs) = unit.docs { // doc pages available

    for doc in docs {

        if let Some(page) = doc.as_man() {

            // `man` page exists 

        }

        if let Some(url) = doc.as_url() {

            // `url` is indicated

        }

    }

}

println!("auto_start (enabled): {:?}", unit.auto_start);

println!("config script : {}", unit.script);

println!("pid: {:?}", unit.pid);

println!("Running task(s): {:?}", unit.tasks);

println!("Memory consumption: {:?}", unit.memory);

```

## TODO

* [ ] parse all known attributes in `from_systemctl`
