Method getModuleInfo

index-import.cpp:98–102

Implementation of ModuleInfoWriterCallback, which is an unusual API. When adding dependencies to Units, the module name is passed not as a string, but instead as an opaque pointer. This callback then maps the opaque pointer to a module name string.

  // but instead as an opaque pointer. This callback then maps the opaque
  // pointer to a module name string.
  static ModuleInfo getModuleInfo(OpaqueModule ref, SmallVectorImpl<char> &) {
    // In this implementation, `mod` is a pointer into `_moduleNames`.
    auto moduleName = static_cast<const StringRef *>(ref);
    return {*moduleName};
  }

  std::set<StringRef> _moduleNames;
