High-Performance Lock-Free Ring-Buffer Queue and Disruptor for Go

Release Notes v0.1.2

Initial public release of ring.queue — a lock-free, high-performance, generic ring buffer queue and disruptor for Go.

Features:

• Features
• Single-producer, multi-consumer (SPMC) disruptor
• Each reader gets its own callback and reads concurrently via its own goroutine
• Advanced ABA-safety: buffer slots only reused after all readers advance
• Sequence/cursor protocol: physical slot index is derived by sequence >> 1 & mask
• Efficient adaptive backoff (busy-spin, yield, sleep) for ultra-fast pipelines

Use cases: HFT, event pipelines, real-time queues, and anywhere you need ultra-low latency with predictable performance.
