yorel::yomm2::policy::trace_output
defined in <yorel/yomm2/policy.hpp>, also provided by <yorel/yomm2/core.hpp>, <yorel/yomm2/keywords.hpp>
struct trace_output;
The trace_output facet enables the YOMM2 runtime to print information about
the data structures used at dispatch time, and how they are derived. This
includes deduction of inheritance lattices, v-table slot allocation, dispatch
table construction, hash parameters, etc. This can help troubleshoot common
errors, like missing class registrations, ambiguities in method definitions,
etc.
The format of the information is not documented, beyond that it is useful. It may change without notice.
