Struct MemorySurbStore 

Source 
pub struct MemorySurbStore {
    pseudonym_openers: Cache<SimplePseudonym, Cache<[u8; 8], ReplyOpener>>,
    surbs_per_pseudonym: Cache<SimplePseudonym, SurbRingBuffer<SURB<Ed25519Suite, HoprSphinxHeaderSpec>>>,
    invalidated_relayers: Arc<RwLock<RawRwLock, HashSet<KeyIdent>>>,
    reporters: Arc<EvictionReporters>,
    cfg: Arc<SurbStoreConfig>,
}
Expand description

Basic SurbStore implementation based on an in-memory cache.

This SURB store offers no persistence, and all SURBs and Reply Openers are lost once dropped.

The instance can be cheaply cloned.
