ECS Library Comparison Project

A comprehensive comparison of 6 different Entity Component System (ECS) libraries in Rust, demonstrating production-ready patterns with type-safe entity handles and command systems.

Overview

This project implements the same pane-dataset management system across multiple ECS libraries, each enhanced with production-ready patterns to provide a realistic comparison of real-world usage.

Featured Libraries

Library Approach Key Features
Flax Relations-based Type-safe handles, modular components, built-in relations, command system
Evenio Event-driven Type-safe handles, command system, registry pattern, event architecture
Hecs + Hierarchy Hierarchy-based Type-safe handles, command system, parent-child relationships
Bevy ECS Component-based Type-safe handles, command system, modern API, wrapper relationships
Sparsey Group-based Type-safe handles, component groups
Flecs Limited Rust API Type-safe handles, simulated command system

Running Examples

Each library implementation is available as a separate binary:

# Run individual examples
cargo run --bin flax_example
cargo run --bin evenio_example  
cargo run --bin hecs_example
cargo run --bin bevy_ecs_example
cargo run --bin sparsey_example
cargo run --bin flecs_example

Production Patterns Demonstrated

All examples showcase production-ready patterns:

  • Type-Safe Entity Handles: Compile-time prevention of entity type mixing
  • Command Systems: Queue-based deferred execution for safer entity lifecycle management
  • Realistic Data: Sensor data examples instead of artificial test data
  • Comprehensive Functionality: Beyond basic component storage and queries

Detailed Analysis

See ECS_COMPARISON.md for an in-depth analysis of each library including:

  • Code examples with production patterns
  • Performance characteristics
  • Readability and maintainability assessment
  • Production-readiness evaluation
  • Detailed recommendations for different use cases

Key Findings

The comparison reveals that Flax Enhanced provides the best combination of type safety, semantic relations, modular organization, and zero-cost abstractions, making it the most suitable choice for large-scale production applications.

Requirements

  • Rust 2024 edition
  • See Cargo.toml for specific dependency versions
