LoadExtensionGuard

Struct LoadExtensionGuard 

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

feature = "load_extension" RAII guard temporarily enabling SQLite extensions to be loaded.

§Example

fn load_my_extension(conn: &Connection) -> Result<()> {
    let _guard = LoadExtensionGuard::new(conn)?;

    conn.load_extension(Path::new("my_sqlite_extension"), None)
}

Implementations§

Source§

impl LoadExtensionGuard<'_>

Source

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