drain_ring_buffer()

void MayaFlux::Journal::Archivist::Impl::drain_ring_buffer ( )

inline

Drain all pending ring buffer entries to sinks or console.

Lock-free. Safe to call from any thread. The worker calls this on its normal cadence; error() and fatal() call it synchronously before propagating exceptions or aborting to guarantee visibility.
