Enum ConcreteStateManager 

pub enum ConcreteStateManager {
    Memory(MemoryStateManager),
    Filesystem(FilesystemStateManager),
}

Concrete enum to wrap StateManager implementations This allows using StateManager without dyn (which isn’t object-safe due to generic methods)

Variants

Memory(MemoryStateManager)

Filesystem(FilesystemStateManager)
