Classes
class	ipc::shm::arena_lend::detail::stat::Finalized_shards< Shm_arena_t >
	(Internal-use) Singleton (per-Shm_arena type <=> per-arena-lending SHM-provider – like SHM-jemalloc) into which owners of per-arena TL-shards (of type Sharded_stats) can deposit such TL-shards that are finalized (will never be updated with new measurements again) + can no longer be stored in TL-state objects; and from which stat-consumption code can read and still aggregate these finalized but still fully valid stat-shards.

Namespaces
namespace	ipc
	Catch-all namespace for the Flow-IPC project: A library/API in modern C++17 providing high-performance communication between processes.
namespace	ipc::shm
	Modules for SHared Memory (SHM) support.
namespace	ipc::shm::arena_lend
	ipc::shm sub-module providing the SHM-provider family based on the arena-lending paradigm: each process allocates in its own arena(s), lending the resulting objects to other processes, which can read them but not allocate (nor deallocate) in that arena.
namespace	ipc::shm::arena_lend::detail
	Segregated private stuff for ipc::shm::arena_lend.
namespace	ipc::shm::arena_lend::detail::stat
	Stats-related sub-namespace, for ADL segregation and general organization.

Functions
template<typename Shm_arena >
void	ipc::shm::arena_lend::detail::stat::sharded_stats (const Shm_arena &shm_arena, Sharded_stats *target_stats)
	Assembles and outputs the current stats tracked by the obj-DB module (as anchored by Thread_lcl_obj_db_admin). More...
template<typename Shm_arena >
void	ipc::shm::arena_lend::detail::stat::sharded_stats_reset (const Shm_arena &shm_arena, Sharded_stats *target_stats)
	Resets Sharded_stats; companion to sharded_stats(). More...
template<bool CONSUME_ELSE_RESET, typename Shm_arena >
void	ipc::shm::arena_lend::detail::stat::sharded_stats_impl (const Shm_arena &shm_arena, Sharded_stats *target_stats)
	Helper: implements sharded_stats() or sharded_stats_reset(). More...
