Trait StatementParent 

pub unsafe trait StatementParent { }

Implementers of this trait are guaranteed to keep a connection alive and in connected state for the lifetime of the instance.

E.g. super::Connection is not a StatementParent, since it is not guaranteed to keep the connection alive. Nor would it close the connection at the end of the lifetime on Drop.

Safety

Instance must keep the connection it owns alive and open.

Implementations on Foreign Types

impl StatementParent for Arc<Connection<'_>>

We need to implement StatementParent for Arc<Connection> in order to be able to express ownership of a shared connection from a statement handle. This is e.g. needed for ConnectionTransitions::into_cursor.

Safety:

Arc<Connection> wraps an open Connection. It keeps the handle alive and valid during its lifetime.
