digitalmars.D - D libraries in other languages

If I made a D library, how easy would it be to use it in other 
languages (C, C++, Go, and Rust)?

D interfaces directly with C, so no problem there. As far as C++ it should work just as well, there are only a very few quirks with that. Anything that can interface to C can interface just as easily to D.

Approximately equally challenging as C++. You basically depend on `extern(C)`. In D you may gain one substantial advantage, in that you might create a system to automatically wrap the D-facing API in `extern(C)` export shims. So perhaps you can automate a lot of `extern(C)` boilerplate...

You automate pretty much all of it: https://github.com/kaleidicassociates/autowrap

As others have mentioned, D can interface with C. D can also interface with C++ and with Objective-C. It depends on which language you want to interface with, you mentioned C++. -- /Jacob Carlborg
