+`[MetaProxy(typeof(MetaProxyType))]` атрибут для гибкой настройки метаданных. Он позволяет обходить ограничения обычных атрибутов (например, невозможность передавать в них неконстантные данные) и задавать метаданные программно. Кроме того, метаданные, полученные через `MetaProxy`, наследуются.

 Вспомогательный тип с набором методов для отладки и логирования. Реализован как статический класс вызывающий методы Debug-сервисов. Debug-сервисы - это посредники между EcsDebug и инструментами отладки среды. Такая реализация позволяет не изменяя отладочный код, менять его поведение или переносить проект в другие среды, достаточно только реализовать соответствующий Debug-сервис.

+
+The `[MetaProxy(typeof(MetaProxyType))]` attribute enables flexible metadata configuration. It allows bypassing the limitations of regular attributes (for example, the inability to pass non-constant data into them) and setting metadata programmatically. Furthermore, metadata obtained via `MetaProxy` is inherited.
+
+The API resembles `[DebuggerTypeProxy]`, but instead of an object instance, it accepts a Type. The class for `MetaProxy` must inherit from `MetaProxyBase`.
+
+Usage example:
+
+``` c#
+// Applying the attribute
+[MetaProxy(typeof(UnityComponent<>.MetaProxy))]
+// In this example, UnityComponent wraps a Unity component
+public struct UnityComponent<T> where T : Component
+{
+    // ...
+
+    // Implementation of MetaProxyBase. MetaProxy copies the metadata of the wrapped type
+    // so that its metadata is displayed in the Unity inspector.
+    private class MetaProxy : MetaProxyBase

+        public override string Name { get { return Meta?.Name; } }

 Provides methods for debugging and logging. Implemented as a static class that forwards calls to a Debug service. Debug services act as intermediaries between environment-specific debugging systems and EcsDebug, enabling portability.
