Enum Durability 

pub enum Durability {
    Memory,
    Async,
    Local,
}

Logical durability contract (research D10). Local is the default and guarantees the commit is durable on this node before it is acknowledged. Async does not fsync: with redb 4.x the commit is not persisted until a later Local commit or checkpoint, so an acknowledged Async commit can be lost on a crash, power loss, or hard kill. It is intended only for re-importable bulk input, not as a weaker consistency mode. Memory is only meaningful for in-memory stores.

Variants

Memory

In-memory only; no durable backend.

Async

Not fsynced and not persisted until a later Local commit or checkpoint; an acknowledged commit can be lost on any crash. For re-importable bulk input only.

Local

Durable on this node before acknowledgement (default).
