low latency tools - rust

This toolkit provides core primitives designed for building high-performance, low-latency applications, specifically targeting Single-Producer Single-Consumer (SPSC) architectures like Limit Order Books.

[x] Atomic Ring Buffer (SPSC): A raw, wait-free, fixed-size ring buffer for single-producer, single-consumer scenarios. Optimized with cache-line padding and Acquire/Release semantics. (v0.1.0)

[x] SPSC Channel: A hybrid channel wrapper around the Atomic Ring Buffer. Combines nanosecond-scale lock-free latency with the CPU efficiency of Condvar blocking during idle periods. (v0.2.0)

[x] CPU Affinity-Aware Thread Pool: Utilities to enumerate cores and pin threads to specific CPU cores. Critical for isolating the "hot path" (Matching Engine) from OS scheduler jitter

[x] Object Pool: A thread-safe system for recycling fixed-size objects (e.g., Orders) to avoid the non-deterministic latency of the global allocator. (v0.3.0)

[x] Arena Allocator: A batch-reset bump allocator for short-lived events (e.g., Market Data updates). Allows zero-cost allocation/deallocation cycles per tick. (v0.4.0)

[x] Non-Blocking Logger: A high-performance logging facility that offloads I/O to a pinned background thread via an SPSC channel, ensuring the critical path never blocks on disk or console. (v0.6.0)
