Crate pybevy_storage 

PyO3-free storage primitives for PyBevy

This crate provides the foundational storage types that are independent of PyO3, enabling reuse from both the CPython (PyO3) and RustPython/WASM backends.

Storage Primitives

• ValidityFlag / ValidityFlagWithMode - Runtime validity tracking
• ValidityGuard - RAII guard for system execution scope
• ValueStorage<T> - Generic storage for Copy types (Vec3, Quat, etc.)
• FieldStorage<T> - Generic storage for non-Copy types (TextureAtlas, etc.)
• ComponentStorage<T> - Generic storage for ECS components
• ResourceStorage<T> - Generic storage for ECS resources
• AssetStorage<T> - Generic storage for Bevy assets
• ListStorage<T> - Generic storage for Vec fields
• BorrowableStorage / FromBorrowedStorage - Traits for borrowed field access
