/// Statement handle which also takes ownership of Connection
pub struct StatementConnection<'env> {

(we don't want this because I guess only one statement at a time)

/// Prepared statements can only be used with the connection that created them.
pub struct Statement(Arc<StatementInner>);

(we don't need an Arc for rusqlite because connection are not Sync)
