Crate upnp-rs
A Rust crate providing basic Universal Plug and Play (UPnP) protocol implementations.
Implements the core protocols of the UPnP Device Architecture (UDA), specifically the discovery protocol for control points to search for, and devices to notify of, device and service availability.
UPnP technology allows devices to connect seamlessly and to simplify network implementation in the home and corporate environments — Open Connectivity Foundation.
Usage
Add the following to your Cargo.toml; currently this crate has no optional features.
upnp-rs = "0.1"
API
The main client interface is the discovery
module that provides search
and notify
capabilities. Over time
the description
module will be completed for the parsing and generation of device description messages. The
following diagram shows the basic structure of the library with the two API modules relying on implementations of
HTTPMU/HTTPU and SOAP respectively.

Example
use upnp_rs::SpecVersion;
use upnp_rs::ssdp::search::*;
let mut options = Options::default_for(SpecVersion::V10);
options.search_target = SearchTarget::RootDevices;
match search_once(options) {
Ok(responses) => {
println!("search returned {} results.", responses.len());
for (index, response) in responses.iter().enumerate() {
println!("{}: {:#?}", index, response);
}
}
Err(error) => {
println!("search failed with error: {:#?}", error);
}
}
Command-Line
The command-line tool upnp
can be used to perform basic operations using the SSDP API. Primarily these are used
for testing, but the search command can be used for general purpose discovery.
The general form of the command is network-options command command-options, as shown below.
USAGE
upnp [-v|--verbose]+ [--interface=] [--ip-version=] COMMAND
COMMANDS
search [-s|--search-target=] [-d|--domain=] [-w|--max-wait=]
interface
this is the name of a local network interface such asen0
.ip-version
denotes that the client should only use IP version 4 or 6.search-target
denotes the scope of the search, valid values areall
,root
,device:
id
,device-type:
id
, orservice-type:
id
,domain
a domain to use for device/service types other than the defaultschemas-upnp-org
.max-wait
the wait time for replies, sent to devices to prevent message flooding.
