This is a small implementation of mDNS (Multicast DNS) based service discovery in safe Rust, with a small set of dependencies. Some highlights:
- supports both the client (querier) and the server (responder) uses.
- supports macOS, Linux and Windows.
- supports IPv4 and IPv6.
- works with both sync and async code.
- no dependency on any async runtimes.
We are not using async/.await internally, instead we create a new thread to run a mDNS daemon.
The API interacts with the daemon via flume channels that work easily with both sync and async code. For more details, please see the documentation.
This implementation is based on the following RFCs:
This is still beta software. We focus on the common use cases at hand. And we tested with some existing common tools (e.g. Avahi on Linux, dns-sd on MacOS, and Bonjour library on iOS) to verify the basic compatibility.
Currently this library has the following limitations:
- Only support multicast, no unicast send/recv.
Tested against Rust 1.60.0
