Detailed Description

template<typename Handoff, template< typename > class Atom>
struct folly::detail::LifoSemNode< Handoff, Atom >

Handoff is a type not bigger than a void* that knows how to perform a single post() -> wait() communication. It must have a post() method. If it has a wait() method then LifoSemBase's wait() implementation will work out of the box, otherwise you will need to specialize LifoSemBase::wait accordingly.
