Enum Durability 

pub enum Durability {
    Sync,
    Group,
    None,
}

How writes are made durable.

Variants

Sync

fsync every push and ack (acks unless Builder::durable_acks is off). Strongest, slowest.

Group

Batch concurrent pushes behind a single fsync; acks fsync each by default (see Builder::durable_acks). Same durability as Sync with far less fsync overhead under load.

None

Do not fsync. Fastest, but no durability guarantee: recent items can be lost on a crash (the backend persists on its own schedule, if at all).
