unsized_const_params
#95174)Expand description
A marker for types which can be used as types of const
generic parameters.
These types must have a proper equivalence relation (Eq
) and it must be automatically
derived (StructuralPartialEq
). There’s a hard-coded check in the compiler ensuring
that all fields are also ConstParamTy
, which implies that recursively, all fields
are StructuralPartialEq
.
