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
