Functions

fetch_degrees 🔒

We use this to fetch ALL degrees into memory. We use this instead of a streaming interface. It is necessary because we must update the degree_state_table concurrently. If we obtain the degrees in a stream, we will need to hold an immutable reference to the state table for the entire lifetime, preventing us from concurrently updating the state table.
