cvkg-render-native

Berserker Hero HUD

cvkg-render-native provides platform-native windowing and event loop integration for CVKG desktop applications using winit and AccessKit.

Boundaries and Responsibilities

This crate acts as the host environment for native applications. It does NOT implement low-level GPU drawing (delegated to cvkg-render-gpu). Its responsibilities include:

Managing the OS window lifecycle and event loop via winit.
Bridging the CVKG VDOM to the platform accessibility tree using AccessKit.
Dispatching native input events (Keyboard, Mouse, IME) into the CVKG event system.
Providing high-resolution frame timing and jitter telemetry for performance monitoring.
Managing "Berserker Mode" OS-level scheduler priorities for high-priority rendering.

Public API Overview

Entry Points

NativeRenderer::run<V: View>(view: V): The primary entry point for launching a CVKG desktop application.

Key Types

NativeRenderer: Implements the Renderer trait by wrapping a GPU-accelerated Surtr instance.
App: The internal winit application handler managing windows and GPU contexts.
NativeAssetManager: A concrete asset loader for the local filesystem using arc-swap for lock-free reads.

Critical Features

Kinetic Injection: Translates window movement into "Rage" telemetry for dynamic UI effects.
ShieldWall Integration: Automatic generation of accessibility trees from VNodes.

Usage Example

use cvkg_render_native::NativeRenderer;
use cvkg_core::View;

fn main() {
    let app_view = MyApp::new();
    NativeRenderer::run(app_view);
}

Known Limitations

Multi-window support is implemented but experimental; focus management across windows is handled via the VDOM bridge.
Wayland support requires specific system dependencies (see root README).
Hardware verification is required; do not rely on mocks for this crate.
