In [CCCB](https://berlin.ccc.de/), there is a big pixel matrix hanging on the wall. It is called  "Service Point
Display" or "Airport Display".
This repository contains a library for parsing, encoding and sending packets to this display via UDP.

### Installation

```bash
# release version
cargo add servicepoint2

# development version
cargo add --git https://github.com/kaesaecracker/servicepoint.git
```

### Example

```rust
fn main() {
    // establish connection
    let connection = servicepoint2::Connection::open("172.23.42.29:2342")
        .expect("connection failed");

    // clear screen content
    connection.send(servicepoint2::Command::Clear)
        .expect("send failed");
}
```

More are available in the `examples` folder.

### Features

This library has multiple compression libraries as optional dependencies.
If you do not need compression/decompression support you can disable those features.
In the likely case you only need one of them, you can include that one specifically.

```toml
[dependencies.servicepoint2]
git = "https://github.com/kaesaecracker/servicepoint.git"
default-features = false
features = ["compression-bz"]
```
