FloatOrd wrapper that implements Ord, Eq, Hash for floats by defining a specific ordering where all NaN values are equal and less than numbers. Solves the fundamental problem of float comparison in collections and sorting. Demonstrates thoughtful edge case handling in a reusable utility.

Generic bounding volume abstractions with BoundingVolume trait and IntersectsVolume trait for intersection tests. Provides a clean, reusable interface for collision detection, spatial queries, and frustum culling applicable across many domains. Shows excellent trait-based design allowing different volume types (spheres, boxes, etc.) to be used interchangeably.

Computed states system that automatically derives state from source states using a compute function. Implements the ComputedStates trait with source dependencies and calculation logic. Represents a clean, reusable pattern for state management in any application, demonstrating proper encapsulation of derived state logic.

Asset event system defining specific event types for asset lifecycle tracking (Added, Modified, Removed, Unused, LoadedWithDependencies, AssetLoadFailed). Provides a comprehensive, reusable pattern for tracking asset state changes in any asset management system. Shows excellent attention to detail in covering all asset lifecycle stages with specific event types.
