<a id="level"></a>

### Level

```cpp
enum Level
```

[Defined in src/base/include/icy/logger.h:38](https://github.com/auscaster/icey/blob/main/src/base/include/icy/logger.h#L38)

Logging severity levels used by [Logger](https://auscaster.com/icey/docs/api-reference/icy-Logger.md#logger) and [LogChannel](https://auscaster.com/icey/docs/api-reference/icy-LogChannel.md#logchannel).

| Value | Description |
|-------|-------------|
| `Trace` | Most verbose diagnostic output. |
| `Debug` | Debug-only diagnostic output. |
| `Info` | Normal informational output. |
| `Warn` | Warning output for recoverable problems. |
| `Error` | [Error](https://auscaster.com/icey/docs/api-reference/icy-Error.md#error) output for failed operations. |
| `Fatal` | Fatal output immediately before termination. |

---

<a id="byteorder"></a>

### ByteOrder

```cpp
enum ByteOrder
```

[Defined in src/base/include/icy/byteorder.h:31](https://github.com/auscaster/icey/blob/main/src/base/include/icy/byteorder.h#L31)

Byte-order policy used when reading or writing multi-byte integers.

| Value | Description |
|-------|-------------|
| `Network` | Default, use network byte order (big endian). |

---

<a id="packetretention"></a>

### PacketRetention

```cpp
enum PacketRetention
```

[Defined in src/base/include/icy/packetstream.h:202](https://github.com/auscaster/icey/blob/main/src/base/include/icy/packetstream.h#L202)

Describes how an adapter treats incoming packet lifetime beyond the current synchronous call chain.

Borrowed adapters must finish using the packet before emit()/process() returns. Cloned and Retained adapters are explicit ownership boundaries: callers may mutate or free borrowed input only after such a boundary, or after the whole synchronous write/emit call has returned.

| Value | Description |
|-------|-------------|
| `Borrowed` | Packet is only used synchronously during the current emit/process call. |
| `Cloned` | Adapter makes its own copy before deferred or asynchronous use. |
| `Retained` | Adapter retains the original packet object beyond the current call chain. |

---

<a id="packetflags"></a>

### PacketFlags

```cpp
enum PacketFlags
```

[Defined in src/base/include/icy/packetstream.h:211](https://github.com/auscaster/icey/blob/main/src/base/include/icy/packetstream.h#L211)

Flags which determine how the packet is handled by the [PacketStream](https://auscaster.com/icey/docs/api-reference/icy-PacketStream.md#packetstream).

| Value | Description |
|-------|-------------|
| `NoModify` | The packet should not be modified by processors. |
| `Final` | The final packet in the stream. |

### packetSlot

```cpp
template<class Class, class RT, class PT, class IT = IPacket> std::shared_ptr< internal::Slot< RT, IT & > > packetSlot(Class * instance, RT(Class::*)(PT &) method, int id = -1, int priority = -1)
```

[Defined in src/base/include/icy/packetsignal.h:45](https://github.com/auscaster/icey/blob/main/src/base/include/icy/packetsignal.h#L45)

Creates a signal slot that filters by packet subtype `PT` before invoking `method`.

The returned slot is connected to a `PacketSignal` (which broadcasts `IPacket&`). The slot performs a `dynamic_cast` on each received packet; if the cast succeeds, the listener method is called with the derived type `PT`. Non-matching packets are silently ignored.

#### Returns
A shared slot suitable for connecting to a `PacketSignal`.

#### Parameters

| Parameter | Type | Description |
|-----------|------|-------------|
| `instance` | `Class *` | Pointer to the listener object. |
| `method` | `RT(Class::*)(PT &)` | Member function pointer on `Class` accepting a `PT&`. |
| `id` | `int` | Optional slot identifier; -1 for automatic assignment. |
| `priority` | `int` | Optional slot priority; higher values run first. |
