3/// Provides access to the raw underlying ODBC handle. This trait is implemented for environment,
4/// connection and statement handles. [`Self::handle_type`] allows to determine the type of the
5/// handle at runtime. Yet, this information is not in the type system. This is useful for
6/// operations, which must work with all handle types. E.g. fetching diagnostics.

10/// The handle provided by `as_handle` must be valid and match the type returned by `handle_type`.
