# hashtree-index
Content-addressed B-tree indexes for hashtree.
The crate builds deterministic index trees on top of `hashtree-core`, so index
roots can be stored, replicated, and compared the same way as file trees.
Current uses include:
- key/value lookup over immutable tree roots
- link indexes that point directly at content-addressed blobs
- derived search indexes with tokenized prefix lookup and ranked results
- cross-language index interoperability with the TypeScript implementation
