This is a high-performance native event loop abstraction for D, focused on asynchronous I/O and GUI message integration. The API is callback (delegate) based. For a higher level fiber based abstraction, take a look at vibe.d.
The API documentation is part of vibe.d:

¹ planned, but not currenly implemented
The following compilers are tested and supported:
- DMD 2.103.0
- DMD 2.086.1
- LDC 1.32.0
- LDC 1.16.0

¹ Manually, by adopting the X11 display connection socket
² Systems other than Linux use a polling implementation
- Error code reporting
- Enqueued writes
- Use the type system to prohibit passing thread-local handles to foreign threads
