Crate ndn_store 

ndn-store – Forwarding tables and content storage

Implements the core forwarding-plane data structures: FIB, PIT, Content Store, and strategy table. All tables are designed for concurrent access (using DashMap or sharding) on the packet-processing hot path.

Key types

• NameTrie – generic name-prefix trie used by FIB and strategy table.
• Fib / FibEntry – Forwarding Information Base (longest-prefix match).
• Pit / PitEntry – Pending Interest Table with in/out records.
• ContentStore trait – pluggable cache interface.
• LruCs – single-threaded LRU content store.
• ShardedCs – sharded wrapper for concurrent CS access.
• [FjallCs] – persistent on-disk content store (requires fjall feature).
• NullCs – no-op store for testing or cache-less operation.
• ObservableCs – decorator that emits CsEvents on insert/evict.
• StrategyTable – prefix-to-strategy mapping.
• CsAdmissionPolicy – trait controlling which Data packets are cached.

Feature flags

• fjall – enables [FjallCs], the persistent content store backend.
