Crate rupnp

An asynchronous library for finding UPnP control points, performing actions on them and reading their service descriptions. UPnP stand for Universal Plug and Play and is widely used for routers, WiFi-enabled speakers and media servers.

Specification: http://upnp.org/specs/arch/UPnP-arch-DeviceArchitecture-v2.0.pdf

Example usage:

The following code searches for devices that have a RenderingControl service and prints their names along with their current volume.

use futures::prelude::*;
use std::time::Duration;
use rupnp::ssdp::{SearchTarget, URN};

const RENDERING_CONTROL: URN = URN::service("schemas-upnp-org", "RenderingControl", 1);

#[tokio::main]
async fn main() -> Result<(), rupnp::Error> {
    let search_target = SearchTarget::URN(RENDERING_CONTROL);
    let devices = rupnp::discover(&search_target, Duration::from_secs(3)).await?;
    pin_utils::pin_mut!(devices);

    while let Some(device) = devices.try_next().await? {
        let service = device
            .find_service(&RENDERING_CONTROL)
            .expect("searched for RenderingControl, got something else");

        let args = "<InstanceID>0</InstanceID><Channel>Master</Channel>";
        let response = service.action(device.url(), "GetVolume", args).await?;

        let volume = response.get("CurrentVolume").unwrap();

        println!("'{}' is at volume {}", device.friendly_name(), volume);
    }

    Ok(())
}

Structs

Device

A UPnP Device. It stores its Uri and a DeviceSpec, which contains information like the device type and its list of inner devices and services.

DeviceSpec

Information about a device.

Service

A UPnP Service is the description of endpoints on a device for performing actions and reading the service definition. For a list of actions and state variables the service provides, take a look at scpd.

Enums

Error

The UPnP Error type.

Functions

discover

Discovers UPnP devices on the network.
