Is there a specification of the wire protocol?

[John-Nagle]

I've looked through the docs, and I can't find the spec for the wire protocol.

(Why? I may have to implement it in Rust.)

Hey John, at this time we don't have documentation of that since it's not part of the public API of LSL. There's quite a lot that a client would have to support to be fully compatible (discovery, time sync, protocol negotiation, serialization), and a high risk of subtle implementation bugs that cause client-side breakage if things aren't done extremely carefully. However, there are existing Rust bindings for liblsl already, maybe those would help with your issue?

You would have to implement at least the discovery protocol (UDP multicast + XPath matching), the time synchronization protocol and the data exchange protocol.

For the latter, the v100 data exchange protocol is tested extensively (https://github.com/sccn/liblsl/blob/master/testing/int/serialization_v100.cpp), even though the data format still isn't documented.

If there were someone to attempt a reimplementation, I could provide an overview and answer questions.
