Grid Engine

A flexible and efficient Rust library for managing 2D grid-based layouts with automatic collision handling and dynamic vertical expansion.

Features

• 🎯 Automatic collision detection and resolution
• 📏 Dynamic grid expansion on the y-axis
• 🔄 Event system for tracking grid changes
• 🛡️ Strong type safety and error handling
• 📦 No unsafe code

Installation

Add this to your Cargo.toml:

[dependencies]
grid_engine = "0.1.0"

Usage

Here's a basic example of using grid_engine:

use grid_engine::grid_engine::GridEngine;

// Create a new 10x12 grid
let mut grid = GridEngine::new(10, 12);

// Add a change listener to track modifications
grid.events.add_changes_listener(Box::new(|event| {
    println!("Grid changed: {:?}", event.changes);
}));

// Add items to the grid (with automatic collision handling)
grid.add_item("box1".to_string(), 0, 0, 2, 2).unwrap();
grid.add_item("box2".to_string(), 0, 0, 2, 2).unwrap(); // Will be repositioned to avoid collision

// Move items
grid.move_item("box1", 2, 2).unwrap();

// Remove items
grid.remove_item("box2").unwrap();
