Function load_vector_extension 

pub fn load_vector_extension(
    conn: &Connection,
    path: Option<&Path>,
) -> Result<()>

Load the sqlite-vector extension

The extension binary should be available at the given path. Pre-built binaries can be downloaded from: https://github.com/sqliteai/sqlite-vector/releases

Platform-specific defaults

If no path is provided, defaults to:

• Linux: ./libsqlite_vector.so
• macOS: ./libsqlite_vector.dylib
• Windows: ./sqlite_vector.dll

Safety

This function uses unsafe because rusqlite::Connection::load_extension calls sqlite3_load_extension, which loads a native shared library (.so / .dylib / .dll) into the current process. Loading an untrusted library can execute arbitrary code.

Requirements for safe usage:

• The extension binary must come from a trusted, verified source (e.g., official releases).
• The path argument should never be derived from user-supplied input.
• Consider validating file checksums before loading in production deployments.
