Package libboost_coroutine1.76.0: Information

Boost.Coroutine provides templates for generalized subroutines which
allow suspending and resuming execution at certain locations. It
preserves the local state of execution and allows re-entering
subroutines more than once.

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.
