Struct RefusedLen 

pub struct RefusedLen(pub Option<usize>);

Issues 1612 / 1632 — the size a refused take needed, as a drop log prints it: the number, or ? when unknown. No allocator.

RefusedLen::for_error is the one rule for WHICH refusal may carry a size: only BufferTooSmall, the caller’s-buffer refusal a take measures. MessageTooLarge is the backend’s own staging buffer refusing before any take saw a length, so a size recorded by an earlier BufferTooSmall must not be printed beside it. The C++ subscription drop log and nros-node’s arena drop log both read it from here, so the two cannot disagree.
