core
Shared core building blocks reused across the Lantern monorepo (server, client, CLI). Collects general-purpose data structures and algorithms that are not specific to the gRPC/transport layer.
Subpackages
| Path | Description |
|---|---|
cache/ |
Generic in-memory cache with TTL. |
collection/ |
Generic collections: priority queue (pq), set, slice helpers. |
concurrent/ |
Concurrency primitives, including a typed pub/sub (concurrent/pubsub). |
graph/ |
In-memory graph model and traversal/scoring helpers. |
graphcache/ |
Graph-specialized cache: TTL'd vertices and additive decaying edges, with an optional prefix index. The server's primary store. |
model/function/ |
Functional-style type aliases used across the other packages. |
nlp/ |
Lightweight NLP helpers. |
These packages originated in a standalone toolkit repository and were folded into this monorepo when the projects were consolidated. They have no dependencies on the rest of Lantern and are safe to import from anywhere in this module.
