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.

Installation

cargo add servicepoint

or

[dependencies]
servicepoint = "0.10.0"

Examples

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

    // clear screen content
    connection.send(servicepoint::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.
