Interface RawConnectionOperation<T>

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface RawConnectionOperation<T>
Performs raw JDBC work with a Connection managed by Database.useRawConnection(RawConnectionOperation).

The connection is valid only for the duration of the callback. Do not close it, retain it, manage transaction lifecycle directly from it, or mutate connection-wide state such as schema, catalog, client info, holdability, type map, or network timeout. Pyranid guards those operations and routes Statement.getConnection() and DatabaseMetaData.getConnection() back to the managed handle. ResultSet.getStatement() returns a guarded statement, and guarded JDBC objects refuse driver-specific unwrap(...) calls that could expose the driver's underlying connection.
