Module sync 

Synchronization primitives for low-latency applications.

This module provides:

• Spinlock - A simple spinlock with RAII guard
• Barrier - Thread barrier for coordination
• asm::atomic - Low-level atomic operations via inline assembly
• asm::fence - Memory fences and timing utilities (RDTSC)

Architecture

All primitives are designed for x86_64 and use cache-line alignment to prevent false sharing. The asm submodule provides direct access to CPU instructions for maximum performance.

Re-exports

pub use asm::atomic;

pub use asm::fence;
