Struct rusqlite::LoadExtensionGuard

pub struct LoadExtensionGuard<'conn> { /* private fields */ }

This is supported on crate feature load_extension only.

RAII guard temporarily enabling SQLite extensions to be loaded.

Example

fn load_my_extension(conn: &Connection) -> Result<()> {
    unsafe {
        let _guard = LoadExtensionGuard::new(conn)?;
        conn.load_extension("trusted/sqlite/extension", None)
    }
}

Implementations

impl LoadExtensionGuard<'_>

pub unsafe fn new(conn: &Connection) -> Result<LoadExtensionGuard<'_>>

Attempt to enable loading extensions. Loading extensions will be disabled when this guard goes out of scope. Cannot be meaningfully nested.

Safety

You must not run untrusted queries while extension loading is enabled.

See the safety comment on Connection::load_extension_enable for more details.
