aetheris-ecs-bevy

Bevy ECS integration for the Aetheris Protocol.

Overview

This crate provides an implementation of the WorldState trait from aetheris-protocol specifically for the Bevy ECS. It bridges the gap between the network protocol and Bevy's entity-component system.

Technical Specifications

• Adapter: BevyWorldAdapter
• Capability: Bridge for bevy_ecs.
• Determinism: Uses rand_chacha::ChaCha8Rng for all internal seeded logic.
• Hot-Path Contract: Implements the Zero Heap Allocation mandate for extract_deltas.

Performance & Hardening (VS-07)

This crate is the primary target for Aetheris performance hardening.

Zero-Allocation Benchmarks

The ecs_pipeline benchmarks use alloc_counter to verify that world-state extraction does not allocate on the heap after the initial warmup.

rtk cargo bench --bench ecs_pipeline

Deterministic State Hashing

BevyWorldAdapter implements state_hash() to facilitate bit-perfect regression testing. It hashes:

• NetworkId (sorted for stability)
• TransformComponent (bit-casted floats)
• ShipStatsComponent

Usage

Add this to your Cargo.toml:

[dependencies]
aetheris-ecs-bevy = "0.8.0"
