Struct MemoryStatsRegistry 

pub struct MemoryStatsRegistry {
    pub overflow_count: AtomicU64,
    /* private fields */
}

Global registry for cross-thread memory statistics

Fields

overflow_count: AtomicU64

Count of threads that couldn’t get a slot

Implementations

impl MemoryStatsRegistry

pub fn register(&self) -> Option<usize>

Register a thread and get its slot index

Returns Some(index) if a slot was claimed, None if registry is full. Uses the current thread’s ID as the identifier.

pub fn update_arena(&self, slot_idx: usize, arena_bytes: usize)

Update arena stats for a slot

Safety

Caller must own the slot (be the thread that registered it)

pub fn update_pool(&self, slot_idx: usize, free_count: usize, capacity: usize)

Update pool stats for a slot

Safety

Caller must own the slot (be the thread that registered it)

pub fn increment_pool_allocations(&self, slot_idx: usize)

Increment pool allocation counter

pub fn aggregate_stats(&self) -> AggregateMemoryStats

Get aggregated memory statistics across all threads

pub fn per_thread_stats(&self) -> impl Iterator<Item = ThreadMemoryStats> + '_

Iterate over per-thread statistics (for detailed diagnostics)

pub fn capacity(&self) -> usize

Get registry capacity
