Enum convergence::connection::ConnectionError

pub enum ConnectionError {
    Protocol(ProtocolError),
    ErrorResponse(ErrorResponse),
    ConnectionClosed,
}

Describes an error that may or may not result in the termination of a connection.

Variants

Protocol(ProtocolError)

A protocol error was encountered, e.g. an invalid message for a connection’s current state.

ErrorResponse(ErrorResponse)

A Postgres error containing a SqlState code and message occurred. May result in connection termination depending on the severity.

ConnectionClosed
