Enum DirectoryOutput 

pub enum DirectoryOutput {
    DirectorySubspace(DirectorySubspace),
    DirectoryPartition(DirectoryPartition),
}

DirectoryOutput represents the different output of a Directory.

Variants

DirectorySubspace(DirectorySubspace)

Under classic usage, you will obtain an DirectorySubspace

DirectoryPartition(DirectoryPartition)

You can open an DirectoryPartition by using the “partition” layer
