    // Provided methods
    fn on_acquire(&self, conn: &mut C) -> Result<(), E> { ... }
    fn on_release(&self, conn: C) { ... }
}

A trait which allows for customization of connections.

Provided Methods

fn on_acquire(&self, conn: &mut C) -> Result<(), E>

Called with connections immediately after they are returned from ManageConnection::connect.

The default implementation simply returns Ok(()).

Errors

If this method returns an error, the connection will be discarded.

fn on_release(&self, conn: C)

Called with connections when they are removed from the pool.

The connections may be broken (as reported by is_valid or has_broken), or have simply timed out.

The default implementation does nothing.
