pub enum ConnectionError {
InvalidCString(NulError),
BadConnection(String),

CouldntSetupConfiguration(Error),
// some variants omitted
}

The database returned an error.
The connection URL could not be parsed.
Diesel could not configure the database connection.
Diesel may try to automatically set session specific configuration

This variant is returned if an error occurred executing the query to set
those options. Diesel will never affect global configuration.
