A trait which provides connection-specific functionality.

Associated Types

type Connection: Send + 'static

The connection type this manager deals with.

type Error: Debug + Send + 'static

The error type returned by Connections.

Required methods

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

Attempts to create a new connection.

fn is_valid<'life0, 'life1, 'life2, 'async_trait>(
    &'life0 self,
    conn: &'life1 mut PooledConnection<'life2, Self>
) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>> where
    'life0: 'async_trait,
    'life1: 'async_trait,
    'life2: '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.
