Enum ConnectionError

pub enum ConnectionError {
    __InvalidState,
    ServerError(PgServerError),
    UnexpectedResponse(String),
    Scram(SCRAMError),
    Io(Error),
    Utf8Error(Utf8Error),
    SslError(SslError),
    ParseError(ParseError),
}

Variants

__InvalidState

👎Deprecated: Use invalid_state!

Invalid state error, suggesting a logic error in code rather than a server or client failure. Use the invalid_state! macro instead which will print a backtrace.

ServerError(PgServerError)

Error returned by the server.

UnexpectedResponse(String)

The server sent something we didn’t expect

Scram(SCRAMError)

Error related to SCRAM authentication.

Io(Error)

I/O error encountered during connection operations.

Utf8Error(Utf8Error)

UTF-8 decoding error.

SslError(SslError)

SSL-related error.

ParseError(ParseError)

Trait Implementations
