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.

Executes SQL statements using a simple protocol that does not involve portals.

The standard flow for executing a SQL statement requires parsing the statement, binding it into a portal, and then executing that portal. This function is a wrapper around that complexity with a simpler interface. The provided stmts are executed directly, and their results are returned as a vector of rows, where each row is a vector of JSON objects.

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