Trait std::marker::ConstParamTy
pub trait ConstParamTy: StructuralEq + StructuralPartialEq + Eq { }🔬This is a nightly-only experimental API. (
adt_const_params #95174)
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.
Object Safety
This trait is not object safe.
