Struct AsyncWriter 

pub struct AsyncWriter { /* private fields */ }

Async-compatible writer using mutex-guarded file I/O

This is the portable implementation using parking_lot::Mutex<std::fs::File>. It provides the same API that a future io_uring backend would expose, allowing transparent upgrades on Linux 5.6+.
