Struct FileVectorStore 

pub struct FileVectorStore { /* private fields */ }

File-based vector store with automatic persistence

This implementation provides persistent vector storage using local files. Data is serialized with bincode for performance and compactness.

Implementations

impl FileVectorStore

pub fn new(config: FileConfig) -> Result<Self>

Create new file-based vector store

If the file exists, loads data from disk. Otherwise, creates a new empty store. The parent directory will be created if it doesn’t exist.
