Enum StorageDirection 

pub enum StorageDirection {
    Both,
    OutOnly,
    InOnly,
}

Storage direction of an edge table, derived from the CSR strategies.

Both directions enabled pays double writes and double storage but serves forward and reverse traversal from local rows. Single-direction tables store only one leg and answer the missing direction as empty.

Variants

Both

Outgoing and incoming legs stored.

OutOnly

Only the outgoing leg stored.

InOnly

Only the incoming leg stored.
