ElementType

The xmr::ElementType enum is defined in meta_reader.h (via impl/enum.h). It describes an entity which could be a primitive type or a user-defined type.

The underlying type for ElementType is uint8_t.

Fields

Although many values are defined by ECMA-335, most of them are not legal in metadata files. If the "Xlang type" column is blank, then this value will not be reported by the metadata parser for valid metadata files, although those marked "Used internally" or "Transformed" are physically present in the metadata file but are transformed by the parser into something else, as noted.
