Kobalt Core

Core functionality for the Kobalt UI framework.

Overview

kobalt-core is the heart of the Kobalt framework. It provides all the fundamental building blocks for creating declarative UIs without depending on any specific rendering backend or platform runtime.

Features

• Widget Tree: Composable widget system for building UIs
• Layout System: Flexbox-inspired layout engine (Column, Row)
• State Management: Reactive state with LiveData, ValueNotifier, and ChangeNotifier
• MVVM Infrastructure: ViewModel patterns for separating business logic
• Common Types: Primitive types like Size, Rect, Color

Architecture

This crate is:

• ✅ Platform-agnostic
• ✅ No WGPU dependency
• ✅ Testable with cargo test
• ✅ Portable to any platform
