Astra 1.0.0
Astra ECS v1.0 - High-Performance Entity Component System
🚀 Overview
Astra is a header-only Entity Component System (ECS) library for modern C++20, delivering high performance through archetype-based storage and aggressive optimization techniques.
⚡ Performance Highlights
- ~1.04B entities/second single-component iteration (hot cache)
- ~465M entities/second dual-component iteration
- Sub-nanosecond per-entity overhead in tight loops
- 2x faster batch entity creation vs individual creation
🎯 Key Features
Core Architecture
- Archetype-based storage with automatic entity grouping by component composition
- Structure-of-Arrays (SoA) layout for optimal cache utilization
- 16KB chunk-based allocation aligned to modern CPU cache hierarchies
- O(1) component access via direct ComponentID indexing
Advanced Capabilities
- Relationship graphs - Hierarchical parent-child and bidirectional entity links
- Query system with compile-time iteration optimizations
- Optional components (
Optional<T>) - Exclusion filters (
Not<T>) - Any-of queries (
Any<T...>) - One-of constraints (
OneOf<T...>)
- Optional components (
- Memory defragmentation - Configurable chunk coalescing and archetype cleanup
- Binary serialization with compression support (LZ4/ZSTD)
- Cross-platform SIMD abstractions (SSE2/SSE4.2/AVX2/NEON)
🛠️ Requirements
- C++20 compatible compiler (GCC 11+, Clang 13+, MSVC 2022+)
- Premake5
- Optional: GoogleTest for tests, Google Benchmark for benchmarks
