Struct Partition

Source 
struct Partition<K: Eq + Hash, V> {
    last_read: Instant,
    next_expiry: Instant,
    size: usize,
    records: HashMap<K, Vec<(V, Instant)>>,
}
Expand description

The cached records for a domain.

Fields§

§last_read: Instant

The time this partition was last read at.

§next_expiry: Instant

When the next record expires.

INVARIANT: this is the minimum of the expiry times of the records.

§size: usize

How many records there are.

INVARIANT: this is the sum of the vector lengths in records.

§records: HashMap<K, Vec<(V, Instant)>>

The records, further divided by record key.
