13 | //! The `rt` module provides a narrow set of runtime services, | |
14 | //! including the global heap (exported in `heap`) and unwinding and | |
15 | //! backtrace support. The APIs in this module are highly unstable, | |
16 | //! and should be considered as private implementation details for the | |
17 | //! time being. | |
