# toes-matter

Tiny facade around `rs-matter` for the Toes RGB light flow:

```rust
#![recursion_limit = "256"]

fn main() -> toes_matter::Result<()> {
    env_logger::init_from_env(
        env_logger::Env::default().filter_or(env_logger::DEFAULT_FILTER_ENV, "info"),
    );

    futures_lite::future::block_on(async {
        toes_matter::generate_credentials("./creds").await?;
        toes_matter::provision().await?;
        toes_matter::listen().await
    })
}
```

## Runtime assumptions

- Linux + BlueZ on system D-Bus
- `wpa_supplicant` controlling the Wi-Fi interface
- `wpa_cli`, `ip`, and a DHCP client available
- `rgbled` in `$PATH`
- Avahi/zeroconf for mDNS

## Environment

- `TOES_MATTER_CREDS_DIR` / `MATTER_CREDS_DIR` default: `./creds`
- `TOES_MATTER_STATE_DIR` / `MATTER_KV_DIR` default: `<creds>/state`
- `TOES_MATTER_WIFI_IFACE` / `MATTER_WIFI_IFACE` default: `wlan0`
- `RGBLED_ORDER` default: `grb`

## Development credentials

`generate_credentials()` writes rs-matter's built-in development/test DAC/PAI/CD and the test PAA trust-store cert. These are for local development, not production.
