Rust dbus and dconf gnome api bindings

A friendly API for interacting with gnome shell, freedesktop and other D-Bus services and settings available on Ubuntu gnome.

This project is thought to be used in Sittly a tauri based app, you will see this trending in the examples.

Disclaimer: I'm not a Rust expert, I'm learning Rust and I'm using this project to learn it. If you see something that can be improved, please open an issue or a PR.

Usage

System apps

This app struct is thought to be used in a GUI to display all the apps installed in the system.

Because of that app.icon is a png image that can be encoded in base64 using app.get_base64_icon() and displayed in a GUI.

use gnome_dbus_api::handlers::easy_gnome::apps::Apps;

#[derive(Serialize, Deserialize, Clone)]
struct AppStruct {
    name: String,
    icon: Option<String>,
    description: String,
}
// Init gtk global instance to use gtk related functions
// If you already have a gtk instance running you must skip this step
gtk::init().unwrap();

async fn get_all_apps() -> Result<Vec<AppStruct>, String> {
  let apps_instance = Apps::new();
  let apps = apps_instance.get_apps();
  let apps_struct: Vec<AppStruct> = apps
      .iter()
      .map(|app| {
          let base64 = app.get_base64_icon();
          let app_struct = AppStruct {
              name: app.name.to_string(),
              icon: base64,
              description: match &app.description {
                  Some(description) => description.to_string(),
                  None => String::from(""),
              },
          };
          app_struct
      })
      .collect();
  Ok(apps_struct)
}

Screen

use gnome_dbus_api::handlers::easy_gnome::screen;

async fn brightness_up() -> Result<(), String> {
    screen::step_up().await;
    Ok(())
}
async fn brightness_down() -> Result<(), String> {

async fn get_brightness() -> Result<i32, String> {

    Ok(brightness)
}
async fn set_brightness(value: i32) -> Result<(), String> {
    screen::set_brightness(value).await;
    Ok(())
}

Night light

use gnome_dbus_api::handlers::easy_gnome::nightlight;

fn get_temperature() {
    let temperature: u32 = nightlight::get_temperature();
}

    let temperature: u32 = 3000;
