Struct InboxEntry 

#[repr(C)]
pub struct InboxEntry {
    pub len: AtomicUsize,
    pub seq: AtomicUsize,
    pub overflow: AtomicBool,
}

One ring entry’s bookkeeping: how many bytes of its slot are valid, the reply-correlation token the backend replies against, and whether the request that arrived was larger than the slot.

Per ENTRY, whatever storage the ring is over, and never inline in the per-queryable header – that is the split W1 made and the reason a family can size its own ring without the backend’s table growing a variant.

Fields

len: AtomicUsize

Valid bytes in this entry’s slot.

seq: AtomicUsize

Reply-correlation token. What it means is the backend’s business (the zenoh shim stores a reply-slot index); the ring only carries it from the producer to the consumer.

overflow: AtomicBool

Set when the incoming request exceeded slot_bytes. The payload is then skipped and the consumer reports it, rather than the ring truncating a request into a well-formed-looking short one.
