Reference

This section is designed as a reference and you probably don't want to read it end to end. It is primarily aimed at those implementing and designing tools and low-level libraries, or users who need to do unusual and/or low-level interop work. Hopefully, if you're doing common integration work you mostly won't need this level of detail.

TODO assumes C/C++

• Functions and Methods
• statics and consts - TODO used attribute. Using the no_mangle attribute implicitly implies used. Use extern for external linkage
• Data types
  • Numeric types
  • Strings
  • Pointers, references, and arrays void pointers, fat pointers, const, arrays and slices, null/non-null, single allocation, no pointers into middle of an object, ZSTs, pointers to deallocated (e.g., dangling) mem, invalid metadata in wide pointers
  • structs, tuples, and unions
  • enums
  • properties - send, sync, eq, hash, etc.
  • classes? trait objects?
