 * All functions are on the `spin_sdk::sqlite::Connection` type.
 * Parameters are instances of the `Value` enum; you must wrap raw values in this type.
 * The `execute` function returns a `QueryResult`. To iterate over the rows use the `rows()` function. This returns an iterator; use `collect()` if you want to load it all into a collection.
