// Tests that when we specialize a template class, we require a declaration
// of that class. However, forward-declaring a specialization doesn't
// require a definition.
#include "tests/cxx/specialization_needs_decl-d1.h"
template<> struct TplStruct<int> { };
// Forward-declaring a specialization is the same: we don't require
// the definition.
template<> struct TplStruct<float>;
// Full-using a specialization requires definition of the specialization to be
// included. Not the base template.
// IWYU: Template needs a declaration

/**** IWYU_SUMMARY
tests/cxx/specialization_needs_decl.cc should add these lines:
#include "tests/cxx/specialization_needs_decl-i1.h"
template <typename T> struct TplStruct;
tests/cxx/specialization_needs_decl.cc should remove these lines:
- #include "tests/cxx/specialization_needs_decl-d1.h" // lines XX-XX
The full include-list for tests/cxx/specialization_needs_decl.cc:
#include "tests/cxx/specialization_needs_decl-i1.h" // for Template
template <typename T> struct TplStruct;
