# LckResult

> How to handle success and error responses from LIV Camera Kit (LCK) service operations in Unity without exceptions.

## Description

`LckResult` is the standard return type for `LckService` operations. Instead of throwing exceptions, methods return this structured result containing a success flag, optional error code, descriptive message, and the operation's value. It serves the same purpose as `Result<T>` in `LckCore` but is used by the higher-level service layer.

***

## Usage

Use `LckResult` whenever you call an `LckService` method. Always check `Success` before accessing the value.

```c# theme={null}
var result = _lckService.GetDescriptor();

if (result.Success)
{
    Debug.Log($"Descriptor: {result.Result}");
}
else
{
    Debug.LogError($"Failed ({result.Error}): {result.Message}");
}
```
