Type Members

1.  final case class AuthenticationGSSContinue(data: Array[Byte]) extends AuthenticationRequest with Product with Serializable

   Specifies that this message contains GSSAPI or SSPI data.

   Specifies that this message contains GSSAPI or SSPI data.

   data

   GSSAPI or SSPI authentication data.

2.  final case class AuthenticationMD5Password(salt: Array[Byte]) extends AuthenticationRequest with Product with Serializable

   Specifies that an MD5-encrypted password is required.

   Specifies that an MD5-encrypted password is required.

   salt

   The salt to use when encrypting the password.

3.  trait AuthenticationRequest extends BackendMessage

   Family of BackendMessage relating to authentication.

   Family of BackendMessage relating to authentication. All share the same top-level decoder, which switches on a secondary tag and delegates to secondary decoders.

4.  final case class AuthenticationSASL(mechanisms: List[String]) extends AuthenticationRequest with Product with Serializable

   Specifies that SASL authentication is required.

   Specifies that SASL authentication is required. The message body is a list of SASL authentication mechanisms, in the server's order of preference.

   mechanisms

   Names of supported SASL authentication mechanisms.

5.  final case class AuthenticationSASLContinue(data: ByteVector) extends AuthenticationRequest with Product with Serializable

   Specifies that this message contains a SASL challenge.

   Specifies that this message contains a SASL challenge.

   data

   SASL data, specific to the SASL mechanism being used.

6.  final case class AuthenticationSASLFinal(data: ByteVector) extends AuthenticationRequest with Product with Serializable

   Specifies that SASL authentication has completed.

   Specifies that SASL authentication has completed.

   data

   SASL outcome "additional data", specific to the SASL mechanism being used.

7.  final case class BackendKeyData(pid: Int, key: Int) extends BackendMessage with Product with Serializable

   Cancellation key data.

   Cancellation key data. The frontend must save these values if it wishes to be able to issue CancelRequest messages later.

   pid

   The process ID of this backend.

   key

   The secret key of this backend.

8.  trait BackendMessage extends AnyRef

   Family of messages that are received from the server (the "back end").

   Family of messages that are received from the server (the "back end"). These messages all consist of a leading tag and a length-prefixed payload. This is an open hierarchy because I don't like the aesthetics of a 52-case ADT. We may revisit this but it's ok for now.

9.  case class Bind(portal: String, statement: String, args: List[Option[String]]) extends TaggedFrontendMessage with Product with Serializable
10.  sealed abstract case class Close extends TaggedFrontendMessage with Product with Serializable
11.  implicit final class CodecOps[A] extends AnyVal
12.  case class CommandComplete(completion: Completion) extends BackendMessage with Product with Serializable

    Command-completed response.

    Command-completed response. The command tag is usually a single word that identifies which SQL command was completed.

    - For an INSERT command, the tag is INSERT <oid> <rows>, where rows is the number of rows inserted. oid is the object ID of the inserted row if rows is 1 and the target table has OIDs; otherwise oid is 0. - For a DELETE command, the tag is DELETE rows where rows is the number of rows deleted. - For an UPDATE command, the tag is UPDATE rows where rows is the number of rows updated. - For a SELECT or CREATE TABLE AS command, the tag is SELECT rows where rows is the number of rows retrieved. - For a MOVE command, the tag is MOVE rows where rows is the number of rows the cursor's position has been changed by. - For a FETCH command, the tag is FETCH rows where rows is the number of rows that have been retrieved from the cursor. - For a COPY command, the tag is COPY rows where rows is the number of rows copied. (Note: the row count appears only in PostgreSQL 8.2 and later.)

    completion

    The command tag.
