Nim doesn’t provide safe mode, but it make a distinction between safe and unsafe features. Safe features are those which cannot corrupt memory integrity while unsafe ones can.
There is currently no restrictions for using unsafe features, but a programmer should be aware that they must be used with care.
Here are some unsafe features:
* The ones dealing with raw memory and especially those using pointers. Note that Nim makes a difference between pointers which allow access to raw (untraced) memory and references which allow access to traced memory.
* Type casting which, contrary to type conversion, is a simple assignment of a new type without any conversion to make the value fully compatible with the new type.
* Using <code>cstring</code> variables as no index checking is performed when accessing an element.
