Enum SessionPersistence 

pub enum SessionPersistence {
    Json,
    Journal,
}

Which on-disk persistence strategy Session::save uses.

Json (the default) writes a full Session-shaped snapshot. Journal is the spec §9.8 opt-in and is only ever selected explicitly via the session_persistence = journal config key.

Variants
