servicepoint

In CCCB, there is a big pixel matrix hanging on the wall. It is called "Service Point Display" or "Airport Display".

This crate contains a library for parsing, encoding and sending packets to this display via UDP. The library itself is written in Rust, but can be used from multiple languages via language bindings.

This project moved to git.berlin.ccc.de/servicepoint/servicepoint. The GitHub repository remains available as a mirror.

Examples

// everything you need is in the top-level
use servicepoint::*;

fn main() {
    // establish connection
    let connection = Connection::open("172.23.42.29:2342")
        .expect("connection failed");

    // clear screen content
    connection.send(Command::Clear)
        .expect("send failed");
}

More examples are available in the crate. Execute cargo run --example for a list of available examples and cargo run --example <name> to run one.

Installation

cargo add servicepoint

or

[dependencies]
servicepoint = "0.13.2"

Note on stability

This library can be used for creative project or just to play around with the display. A decent coverage by unit tests prevents major problems and I also test this with my own projects, which mostly use up-to-date versions.

That being said, the API is still being worked on. Expect breaking changes with every minor version bump. There should be no breaking changes in patch releases, but there may also be features hiding in those.

All of this means for you: please specify the full version including patch in your Cargo.toml until 1.0 is released.

Features

This library has multiple optional dependencies. You can choose to (not) include them by toggling the related features.
