Required methods

fn connect<'life0, 'async_trait>(
    &'life0 self
) -> Pin<Box<dyn Future<Output = Result<Self::Connection>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    Self: 'async_trait, 

Attempts to create a new connection.

fn check<'life0, 'life1, 'async_trait>(
    &'life0 self,
    conn: &'life1 mut Self::Connection
) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    Self: 'async_trait, 

Check if the connection is still valid, check background every check_interval.

A standard implementation would check if a simple query like PING succee, if the Connection is broken, error should return.
