pub fn no_materialize(
_any: &mut dyn Any,
_type_hash: u64,
_bytes: Vec<u8>,
) -> Result<Box<dyn SlotValue>, BackendMaterializeError>Expand description
Backend-only no-op materialize entry used by non-Backend roles.
Roles other than Backend never reach the materialize entry
(decode_typed_fill only consults it after confirming the slot
binds to ComponentRole::Backend), so the unused fn pointer
returns a descriptive error rather than panicking.
