Struct MailboxStats 

pub struct MailboxStats {
    pub enqueued: u64,
    pub dequeued: u64,
    pub rejected: u64,
    pub rejected_byte_limit: u64,
    pub dropped_newest: u64,
    pub dropped_oldest: u64,
    pub queued_messages: usize,
    pub queued_bytes: usize,
}

Per-mailbox counters (Relaxed atomics would over-synchronize a hot inbox). Updated only while the mailbox mutex is held — same critical section as enqueue / park — then copied out for host scrapes.

Fields

enqueued: u64

dequeued: u64

rejected: u64

Total refusals under super::OverflowPolicy::Reject, whichever bound was hit.

rejected_byte_limit: u64

Subset of Self::rejected caused by the byte budget rather than the hop count. rejected - rejected_byte_limit is therefore the hop-count share — the two have different remedies, so an operator needs to tell them apart.

dropped_newest: u64

dropped_oldest: u64

queued_messages: usize

Hops queued right now (occupancy, not a counter).

queued_bytes: usize

Bytes charged to the queued hops right now. Compare against the configured super::MailboxBytes to see how close an inbox is to its budget before it starts refusing.
