pub trait WireOwned: Sealed { }Expand description
Marker for CapHashOrRef::Owned payloads that participate in the
content-addressed wire form. Implemented only for Box<Cap> (the
default payload).
It is a deliberately leaf marker — implemented directly for
Box<Cap> with no supertrait that recurses into Cap: Archive — so
gating the wire impls (HashTreeRoot / Encode / Decode / rkyv
Archive / Serialize) of CapHashOrRef<O> on O: WireOwned
resolves by a single lookup, exactly as the original non-generic
impls did (which required nothing of the inline Box<Cap>). Gating on
O: rkyv::Archive instead would re-introduce the cyclic
Box<Cap>: Archive → Cap: Archive bound and overflow the solver.
Engine-private cache payloads (e.g. Box<CachedCap>) deliberately do
not implement it, so a cnode carrying one has no wire impl and
cannot be hashed or serialised — a compile error, strictly stronger
than the runtime Owned panic.
Sealed: only javm-cap implements it.
