Enum RecordSync 

pub enum RecordSync {
    FileAndDirectory,
    FileOnly,
    Nothing,
}

What: Which syncs follow a journal record’s write. Why: A record published by link is whole or absent after a kill whatever the level; the level only decides what a power loss may leave.

In TS you’d write (pseudocode):

type RecordSync = 'file-and-directory' | 'file' | 'nothing';

Variants

FileAndDirectory

The file’s bytes, then its directory entry: the record is a barrier that later steps rely on.

FileOnly

The file’s bytes only: a later record’s directory sync makes the entry durable before anything depends on it, and a name a power loss took anyway leaves the state of a record that was never written.

Nothing

Neither: recovery completes or discards the transaction whatever a power loss left of this record.
