# ClassUtils

ClassUtils is a Godot Engine **singleton** designed to extend GDScript with features currently unavailable natively, specifically focused on **enforcing abstract function implementations**.

## Features

Abstract Function Checking: Automatically identifies if concrete classes fail to implement abstract functions defined in their abstract parent classes.

## How to Use

1. Add as a Singleton:
Add `class_utils.tscn` as a singleton in your Godot project settings.
2. Mark Abstract Classes:
Above your abstract class's `class_name` declaration, add the line:
"@abstract_class"
ex:
"@abstract_class"
class_name MyAbstractClass
extends Node

3. Mark Abstract Functions:
Inside the body of any abstract function, add the following assertion:

func my_abstract_function():
assert(false, ClassUtils.ABSTRACT_FUNCTION_MSG)
# Your abstract function logic (if any default behavior is desired)



# Promise Utility

`Promise` is a helper class designed to simplify asynchronous workflows in GDScript.
It allows you to `await` operations and check results in a structured way.

### Example Usage

var promise: Promise = async_compute_value()
await promise.wait_for_fulfill()
assert(promise.is_correct(), promise.get_error())
var computed_value: float = promise.get_result() as float
