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:
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
