Detailed Description

template<template< typename > class Atom>
struct folly::detail::LifoSemRawNode< Atom >

LifoSemRawNode is the actual pooled storage that backs LifoSemNode for user-specified Handoff types. This is done so that we can have a large static IndexedMemPool of nodes, instead of per-type pools

uint32_t folly::detail::LifoSemRawNode< Atom >::next

The IndexedMemPool index of the next node in this chain, or 0 if none. This will be set to uint32_t(-1) if the node is being posted due to a shutdown-induced wakeup
