Struct ReaderStats 

pub struct ReaderStats {
    pub bytes_received: AtomicU64,
    pub credit_granted_total: AtomicU64,
    pub read_ns: AtomicU64,
    pub decode_ns: AtomicU64,
}

Diagnostic counters shared between a Reader and its FFI handle.

Held by the Reader via Arc so the FFI surface can clone it once at handle-construction time and serve stat reads thereafter without touching the UnsafeCell<Reader> that holds the Reader. That decouples counter reads from the Reader’s borrow stack: a stat getter no longer synthesises a &Reader while a laundered &mut Reader (held by an in-flight ReaderQuery / Cursor) is still on the stack — eliminating the aliasing question entirely.

All four counters are Relaxed — pure counters with no associated happens-before requirement.

Fields

bytes_received: AtomicU64

Total wire bytes (frame header + payload) read off the transport since this connection was opened.

credit_granted_total: AtomicU64

Total bytes granted to the server via CREDIT (0x15) frames since this connection was opened.

read_ns: AtomicU64

Nanoseconds spent in transport.read_frame() since this connection was opened. Saturates at u64::MAX.

decode_ns: AtomicU64

Nanoseconds spent in decode_frame() since this connection was opened. Saturates at u64::MAX.
