What is the difference between Coroutine, Coroutine2 and Fiber?

Question

There are 3 subtle threads with manual context switching with low latency in Boost:

• Boost.Coroutine: http://www.boost.org/doc/libs/1_64_0/libs/coroutine/doc/html/index.html
• Boost.Coroutine2: http://www.boost.org/doc/libs/1_64_0/libs/coroutine2/doc/html/index.html
• Boost.Fiber: http://www.boost.org/doc/libs/1_64_0/libs/fiber/doc/html/index.html

What is the difference between Coroutine1, Coroutine2 and Fiber in Boost?

Answer 1

boost.coroutine ++ 11 API boost.context( , ).

boost.coroutine2 boost.fiber ++ 11 callcc()/ ( , with-current-continue) boost.context.

boost.coroutine boost.coroutine2 , boost.fiber (== lightweigt, coroperative userland-threads, green-threads,...) API, std:: thread.
