Module persistence 

Persistence and freshness checking for vector indices.

Provides content-hash-based staleness detection so vector indices can persist across restarts. When the content hash matches, the existing index is still valid and doesn’t need rebuilding.

Structs

IndexMetadata

Metadata stored alongside a vector index for freshness checking.

Functions

is_index_fresh

Check if an existing vector index is fresh.

load_metadata

Load index metadata from a JSON file.

save_metadata

Save index metadata to a JSON file.
