| bounded_int_div_rem | — |
| downcast | Downcasts FromType to ToType - for types where conversion may fail. If done for wrong types would cause a compiler panic at the Sierra stage. |
| upcast | Upcasts FromType to ToType - for types where conversion is always legal. If done for wrong types would cause a compiler panic at the Sierra stage. |
