# rill-osc

OSC (Open Sound Control) server and networking for remote control of Rill audio graphs.

For graph-integrated OSC sensors, see `rill-patchbay::osc::OscSensor` and
`spawn_osc_sensor` — these use this crate's parsing to feed OSC events into
the rill actor system for parameter mapping.

## Key components

- **`OscServer`** — async UDP server with address-pattern dispatching
- **OSC types** — `OscMessage`, `OscBundle`, `OscPacket`, `OscType` (Int, Float, String, Blob, Timetag)
- **Encode/decode** — complete OSC packet serialization and parsing
- **Pattern matching** — `*` wildcard support for handler registration
- **`TimeTag`** — NTP-format timetag for bundle scheduling

## Usage

```rust
let mut server = OscServer::bind("127.0.0.1:9000").await?;
server.handle("/audio/volume", |msg, _src| {
    if let Some(OscType::Float(val)) = msg.args.first() {
        println!("volume = {}", val);
    }
});
server.run().await?;
```

## Dependencies

Standalone — no rill-core dependency. Uses `tokio` for async UDP.
