pub struct LoadExtensionGuard<'conn> { /* private fields */ }
Available on crate feature load_extension only.
Expand description

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§

source§

impl LoadExtensionGuard<'_>

source

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.
