Implementations§

Saves the specified statement as a prepared statement.

The prepared statement is saved in the connection’s crate::session::Session under the specified name.

Binds a statement to a portal.

Executes a previously-bound portal.

Starts a transaction based on implicit:

  • None: InTransaction
  • Some(1): Started
  • Some(n > 1): InTransactionImplicit
  • Some(0): no change

Cancels the query currently running on another connection.

Ends a transaction.

Fails a transaction.

Dumps the catalog to a JSON string.

Inserts a set of rows into the given table.

The rows only contain the columns positions in columns, so they must be re-encoded for adding the default values for the remaining ones.

Terminates the client session.

Returns a mutable reference to the session bound to this client.

Returns a mutable reference to the inner client.

Cancel safety

This method is cancel safe. If recv is used as the event in a tokio::select! statement and some other branch completes first, it is guaranteed that no messages were received on this channel.
