abseil-str-cat-append¶
Flags uses of absl::StrCat()
to append to a std::string
. Suggests
absl::StrAppend()
should be used instead.
The extra calls cause unnecessary temporary strings to be constructed. Removing them makes the code smaller and faster.
a = absl::StrCat(a, b); // Use absl::StrAppend(&a, b) instead.
Does not diagnose cases where absl::StrCat()
is used as a template
argument for a functor.
