pub(crate) const MAX_WRAPPER_DEPTH: usize = 64;Expand description
Deepest element nesting a wrapper document is allowed before parsing is refused outright.
A real Rx/Tx wrapper is a handful of levels deep: MessageData holding a
few flat fields, one of them (EncodedPayload) an opaque hex string rather
than nested XML. This is headroom over that shape, not a measurement of it —
wide enough that no real wrapper is ever refused, narrow enough that a peer
cannot hide a few thousand levels of nesting inside a field this crate never
otherwise inspects.
