pub fn is_unimplemented_sealed_core_trait(
trait_name: &str,
trait_decls: &TraitDeclRegistry,
) -> boolExpand description
True when trait_name is a compiler-provided sealed core trait
(bock_types::traits::SEALED_CORE_TRAITS) that is NOT declared as a user
trait in trait_decls. Such a bound is the primitive conformance and must be
lowered to the target’s built-in (native ==/comparison/stringification and
the built-in ordered/equality constraint) rather than referenced as a real
trait/interface, which does not exist in any target. Shared by the
generic-bound renderers and the method-call bridge so the two stay in lockstep.
