Enum FsyncPolicy 

pub enum FsyncPolicy {
    EachOp,
    OnSnapshot,
}

When journal appends reach the disk.

Variants

EachOp

Fsync after every appended journal record — every acknowledged mutation survives a power cut. The default: durability is worth microseconds at this write volume.

OnSnapshot

Fsync only at snapshot boundaries. Faster; an OS crash may lose the journal tail written since the last snapshot.
