软件包：libboost-coroutine1.83.0（1.83.0-3.2 以及其他的）

provides a sort of cooperative multitasking on a single thread

This package forms part of the Boost C++ Libraries collection.

Boost.Coroutine provides templates for generalized subroutines which allow multiple entry points for suspending and resuming execution at certain locations. It preserves the local state of execution and allows re-entering subroutines more than once (useful if state must be kept across function calls).

Coroutines can be viewed as a language-level construct providing a special kind of control flow.

In contrast to threads, which are pre-emptive, coroutine switches are cooperative (programmer controls when a switch will happen). The kernel is not involved in the coroutine switches.

The implementation uses Boost.Context for context switching.
