Enum ConnectError 

pub enum ConnectError<ConnectorError, TlsError = Infallible, AuthenticationError = Infallible> {
    Connector(ConnectorError),
    Tls(TlsError),
    Authentication(AuthenticationError),
    Startup(StartupParameterError),
    Protocol(Error),
}

Failure while establishing a client-role connection, distinct from BuildError.

Variants

Connector(ConnectorError)

Startup(StartupParameterError)

Structured startup values were invalid before network establishment.

Protocol(Error)

PostgreSQL framing, startup, authentication, or readiness failed.

impl<ConnectorError, TlsError, AuthenticationError> Error for ConnectError<ConnectorError, TlsError, AuthenticationError>

where ConnectorError: Error + 'static, TlsError: Error + 'static, AuthenticationError: Error + 'static,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
