Using LDC 1.25.1, __debugOverview, __debugExpanded, and __debugStringView do not work as struct methods in the debug visualizer. They do seem to work as member fields.
Similarly, invoking methods on structs in the immediate window gives the following error: "D0001: Error: Expression couldn't be evaluated"
Confirmed working on DMD 2.096.0

Unfortunately, LDC does not emit debug info for member functions, so the debugger doesn't know how to call them or even whether they exist.
Maybe they can be found as a public symbol assuming default mangling.
