## Detailed Description

Dereferencing a valid QDirListing::const_iterator returns a DirEntry object.

DirEntry offers a subset of QFileInfo's API (for example, fileName(), filePath(), exists()). Internally, DirEntry only constructs a QFileInfo object if needed, that is, if the info hasn't been already fetched by other system functions. You can use DirEntry::fileInfo() to get a QFileInfo. For example:

     using ItFlag = QDirListing::IteratorFlag;
     for (const auto &dirEntry : QDirListing(u"/etc"_s, ItFlag::Recursive)) {
         // Faster
         if (dirEntry.fileName().endsWith(u".conf")) { /* ... */ }

         // This works, but might be potentially slower, since it has to construct a
         // QFileInfo, whereas (depending on the implementation) the fileName could
         // be known already
         if (dirEntry.fileInfo().fileName().endsWith(u".conf")) { /* ... */ }
     }
     using ItFlag = QDirListing::IteratorFlag;
     for (const auto &dirEntry : QDirListing(u"/etc"_s, ItFlag::Recursive)) {
         // Both approaches are the same, because DirEntry will have to construct
         // a QFileInfo to get this info (for example, by calling system stat())

         if (dirEntry.size() >= 4'000 /* 4KB */) { /* ...*/ }
         if (dirEntry.fileInfo().size() >= 4'000 /* 4KB */) { /* ... */ }
     }
