Required methods

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

Attempts to create a new connection.

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

Determines if the connection is still connected to the database.

fn has_broken(&self, conn: &mut Self::Connection) -> bool

Synchronously determine if the connection is no longer usable, if possible.
