Constructor & Destructor Documentation

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.

Definition at line 1069 of file SemaConcept.cpp.

TypeRequirement() [2/2]

clang::concepts::TypeRequirement::TypeRequirement ( SubstitutionDiagnostic *  Diagnostic )

inline

Construct a type requirement when the nested name specifier is invalid due to a bad substitution.

The requirement is unsatisfied.
