impl DatabasePool for NoDatabasePool

type TransactionType = NoTransaction

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

Returns a Transaction for the database for which this DatabasePool has connections. If the database types offers specific read replicas, such as AWS Neptune, the connection is to a read replica. If no separate read replicas are offered, the connection is to the same endpoint that serves read/write requests. Read more
