Struct VecConnection 

pub struct VecConnection { /* private fields */ }

A raw SQLite connection with sqlite-vec registered.

This wraps a *mut sqlite3 handle opened via FFI and provides vec-specific operations. The handle points to the same database file as the main libsql::Connection, allowing vec operations (ANN virtual table) alongside normal queries on the main connection.

Implementations

impl VecConnection

pub fn open(db_path: &Path) -> Option<Self>

Open a raw connection to db_path and register sqlite-vec on it.

Returns None if the path can’t be converted to a C string or if opening / extension registration fails.

pub fn execute(&self, sql: &str) -> Result<(), String>

Execute a SQL statement with no parameters.

pub fn prepare(&self, sql: &str) -> Result<VecStmt, String>

Prepare a SQL statement and return a raw handle for manual binding.

The caller is responsible for stepping, reading results, and finalizing via VecStmt.

pub fn handle(&self) -> *mut sqlite3

Get the raw sqlite3 handle (for direct FFI use in store operations).

pub fn last_insert_rowid(&self) -> i64

Return the rowid returned by last_insert_rowid().
