Detailed Description

template<class T>
requires detail::has_trace<T>
struct jam::tracer< T >

Forward a value hook or a cooperative allocation hook.

Visit each live ptr by reference from the supplied value. Nested values share the enclosing allocation's pointer mask. Static trace(visit, ptr<T>) owns allocation claiming and may walk directly between records.

Generate field enumeration and cooperative allocation tracing from a manifest.
