Expand description

Re-export the unified 64-byte aligned buffer type

This type alias maintains backward compatibility while using the consolidated aligned buffer implementation from rusty-common. 64-byte aligned buffer for cache line optimization and false sharing prevention

Aligns data structures to CPU cache line boundaries (typically 64 bytes) to maximize cache efficiency and prevent false sharing in multi-threaded HFT applications.

§Cache Line Benefits

  • Cache efficiency: Entire buffer fits within cache line boundaries
  • False sharing prevention: Eliminates cache ping-ponging between cores
  • Memory bandwidth: Maximizes utilization of cache line transfers
  • Prefetching optimization: Predictable access patterns improve prefetcher efficiency

§HFT Use Cases

  • Per-thread buffers: Eliminate false sharing between trading threads
  • Order book snapshots: Cache-efficient storage of market data
  • Statistics collections: High-frequency counter updates
  • Message buffers: Network I/O optimization
