Enum Durability 

pub enum Durability {
    Buffered,
    Flush,
    Sync,
}

The durability level requested for an append. A stronger level includes the guarantees of the weaker ones; see the crate’s durability contract for the per-platform survival matrix.

Variants

Buffered

Return after bytes are accepted into engine-managed memory; no promise of surviving process or power loss.

Flush

Submit all bytes to the operating system before returning; not promised to survive OS or power loss.

Sync

Invoke the strongest supported file-data synchronization before returning; survives abrupt process termination under the documented model.
