Variants§

§

RawMessage(&'a [u8])

Raw bytes from a client.

§

Initial(Result<InitialMessage<'a>, ParseError>)

Initial message from client.

§

Message(Result<Message<'a>, ParseError>)

Non-initial message from the client.

§

SslReady

SSL is ready.

§

AuthInfo(AuthType, CredentialData)

Provide authentication information. The environment may supply credential data that doesn’t match the auth type. In such cases, the server will try to adapt the auth data appropriately.

Additionally, the environment can provide a “Trust” credential for automatic success or a “Deny” credential for automatic failure. The server will simulate a login process before unconditionally succeeding or failing in these cases.

§

Parameter(String, String)

Once authorized, the server may sync any number of parameters until ready.

§

Ready(i32, i32)

Ready, handshake complete.

§

Fail(PgError, &'a str)

Fail the connection with a Postgres error code and message.
