cuda::experimental::stf::with_location

template<class T>
struct with_location

Value (or reference) plus the call-site source_location of its construction.

Intended as a function parameter type: write with_location<widget> instead of widget so the callee can report file/line. Construction from an argument captures source_location::current() at that call site (overloaded operators cannot take defaulted source_location parameters themselves).

Move-only: may be constructed as a temporary and moved into a by-value parameter, but not copied. T may be a value, lvalue reference, or rvalue reference.
