Enum Persistence 

pub enum Persistence {
    Buffer,
    Sync,
    BufferThenSync,
}

The persistence mode to use on the database.

Variants

Buffer

Buffer the changes but don’t wait for them to be synced to disk.

This can lead to corruption if there is a crash.

Sync

Sync all changes to disk.

This prevents corruption but can be a bit slower.

BufferThenSync

Buffer changes while syncing but then switch to syncing all changes to disk once synced.

This is a compromise between Self::Buffer and Self::Sync.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
