Crate hojicha_rendering 

High-performance rendering optimization for the Hojicha TUI framework

This crate provides differential rendering to minimize terminal updates by tracking and only redrawing changed regions of the UI.

Features

• Differential Rendering: Track dirty regions and only redraw what changed
• Region Coalescing: Automatically merge overlapping dirty regions
• Component Dependencies: Track component relationships for cascading updates
• Checksum-based Change Detection: Detect actual content changes

Example

use hojicha_rendering::DifferentialRenderer;
use ratatui::layout::Rect;

let mut renderer = DifferentialRenderer::new();

// Register UI components
renderer.register_component("header".to_string(), Rect::new(0, 0, 80, 3));
renderer.register_component("content".to_string(), Rect::new(0, 3, 80, 20));

// Mark a component as dirty when it changes
renderer.mark_component_dirty("content");

// Check if rendering is needed
if renderer.component_needs_render("content") {
    // Render the component
}
