ImplicitConversionSequence - Represents an implicit conversion sequence, which may be a standard conversion sequence (C++ 13.3.3.1.1), user-defined conversion sequence (C++ 13.3.3.1.2), or an ellipsis conversion sequence (C++ 13.3.3.1.3).

◆ Kind

Kind - The kind of implicit conversion sequence.

BadConversion specifies that there is no conversion from the source type to the target type. AmbiguousConversion represents the unique ambiguous conversion (C++0x [over.best.ics]p10). StaticObjectArgumentConversion represents the conversion rules for the synthesized first argument of calls to static member functions ([over.best.ics.general]p8).
