Type Alias QlogFileWriter 

pub type QlogFileWriter = Box<dyn Write + Send + Sync>;

Boxed Write returned by make_qlog_writer / make_qlog_writer_from_path.

Producers (e.g. quiche::Connection::set_qlog) typically require Send + Sync; the boxed form keeps the writer object-safe across the compression-vs-no-compression branches.
