Abso1ut3Zer0/nexus — reverse-engineered prompt

Build me a Rust workspace for ultra fast, predictable backend systems, the kind of thing you would use for trading or other real time services where latency spikes are a problem. I want it to feel like a toolbox of small focused pieces, not one giant framework. The main idea should be bounded, preallocated components that avoid surprise allocations and keep behavior consistent under load.

Include the core building blocks people would actually use together, like fast IDs and fixed ASCII or decimal types, slab or pool style memory management, bounded queues and channels, a latest wins slot for snapshots, notifications, rate limiting, timers, low level networking, and zero copy HTTP and WebSocket support. There should also be a runtime story for event driven systems, plus async adapters that work with Tokio for real use.

Please make it usable, with clear examples, sensible docs, and a couple of end to end demos that show these parts working together in a realistic low latency service. If you need details, check current Rust docs online.
