nmrs 🦀

A Rust API for NetworkManager over D-Bus. The goal is to provide a safe and simple high-level API for managing Wi-Fi connections on Linux systems, built on zbus for reliable D-Bus communication.

The project is divided into the following crates:

• nmrs: The core library providing NetworkManager bindings and Wi-Fi management API.
• nmrs-gui: A Wayland-compatible GTK4 graphical interface for NetworkManager.

Getting Started

The best way to get started with nmrs is the API documentation, which includes examples for common operations like scanning networks, connecting to Wi-Fi, and managing connection profiles.

Sample usage

We'll create a simple example that scans for available networks and connects to one. Note that these examples require NetworkManager to be running on your Linux system with D-Bus access, obviously.

Listing Networks

Scan for and display available Wi-Fi networks:

use nmrs::NetworkManager;

#[tokio::main]
async fn main() -> nmrs::Result<()> {
    let nm = NetworkManager::new().await?;
    
    // Scan for networks
    let networks = nm.list_networks().await?;
    
    for net in networks {
        println!(
            "{} - Signal: {}%, Security: {:?}",
            net.ssid,
            net.strength.unwrap_or(0),
            net.security
        );
    }
    
    Ok(())
}

Now let's connect to a network...

Connect to a WPA-PSK protected network:

use nmrs::{NetworkManager, WifiSecurity};

#[tokio::main]
async fn main() -> nmrs::Result<()> {
    let nm = NetworkManager::new().await?;
    
    // Connect to a network
    nm.connect("MyNetwork", WifiSecurity::WpaPsk {
        psk: "password123".into()
    }).await?;
    
    // Check current connection
    if let Some(ssid) = nm.current_ssid().await {
        println!("Connected to: {}", ssid);
    }
    
    Ok(())
}

Error Handling

All operations return Result<T, ConnectionError> with specific error variants:

use nmrs::{NetworkManager, WifiSecurity, ConnectionError};

#[tokio::main]
async fn main() -> nmrs::Result<()> {
    let nm = NetworkManager::new().await?;
    
    match nm.connect("MyNetwork", WifiSecurity::WpaPsk {
        psk: "wrong_password".into()
    }).await {
        Ok(_) => println!("Connected successfully"),
        Err(ConnectionError::AuthFailed) => eprintln!("Authentication failed - wrong password"),
        Err(ConnectionError::NotFound) => eprintln!("Network not found or out of range"),
        Err(ConnectionError::Timeout) => eprintln!("Connection timed out"),
        Err(e) => eprintln!("Error: {}", e),
    }
    
    Ok(())
}

nmrs-gui

This repository also includes nmrs-gui, a Wayland-compatible NetworkManager frontend built with GTK4.

Installation
