| abseil-redundant-strcat-calls |
| ============================= |
| |
| Suggests removal of unnecessary calls to ``absl::StrCat`` when the result is |
| being passed to another call to ``absl::StrCat`` or ``absl::StrAppend``. |
| |
| The extra calls cause unnecessary temporary strings to be constructed. Removing |
| them makes the code smaller and faster. |
| |
| Examples: |
| |
| .. code-block:: c++ |
| |
| std::string s = absl::StrCat("A", absl::StrCat("B", absl::StrCat("C", "D"))); |
| //before |
| |
| std::string s = absl::StrCat("A", "B", "C", "D"); |
| //after |
| |
| absl::StrAppend(&s, absl::StrCat("E", "F", "G")); |
| //before |
| |
| absl::StrAppend(&s, "E", "F", "G"); |
| //after |
