Struct PersistFile

Source 
pub(crate) struct PersistFile {
    file: BufWriter<File>,
    needs_resynch: Result<(), ()>,
    lock: Arc<LockFileGuard>,
}
Expand description

Persistent state file, and associated data

Stored as ReplayLog.file.

Fields§

§file: BufWriter<File>

A file logging fingerprints of the messages we have seen.

§needs_resynch: Result<(), ()>

Whether we had a possible partial write

See the comment inside ReplayLog::check_for_replay. Ok means all is well. Err means we may have written partial data to the actual file, and need to make sure we’re back at a record boundary.

§lock: Arc<LockFileGuard>

Filesystem lock which must not be released until after we finish writing

Must come last so that the drop order is correct
