Enum Durability 

pub enum Durability {
    Record,
    Os,
}

When the log asks the filesystem to make publication metadata durable.

Both settings sync each immutable extent and the bounded head before its generation-bound rename. New data files and their directories are synced before the first referencing head. Filesystem/NFS power-loss guarantees remain mount-specific.

Variants

Record

Additionally request a containing-directory sync after each head rename.

Os

Leave metadata durability after head publication to the operating system. Extent data, first-file directory entries, and staged heads remain synced.
