Method flush_and_sync

crates/commitlog/src/lib.rs:310–317

Write all outstanding transaction records to disk and flush OS buffers. Equivalent to calling [`Self::flush`] followed by [`Self::sync`], but without releasing the write lock in between. # Errors An error is returned if writing to disk fails due to an I/O error. # Panics This method panics if syncing fails irrecoverably.
