◆ TypeRequirement() [1/2]

concepts::TypeRequirement::TypeRequirement ( TypeSourceInfo * T )

Construct a type requirement from a type.

If the given type is not dependent, this indicates that the type exists and the requirement will be satisfied. Otherwise, the SubstitutionDiagnostic constructor is to be used.
