use c++ standard stream function in StrCat will be fail

[fansehep]

If i use the StrCat in this case

std::string test () {
  return absl::StrCat(std::setw(sizeof(uint64_t)), std::setfill('0'), "some other things");
}

it will be fail. I want to know dose abseil-cpp provide similar function to control output?

The closest thing Abseil has to what I think you are trying to do is absl::StrFormat(), but it requires that you use printf-style format strings. There is also absl::StreamFormat() if you want to use a format string in a stream.

If you are looking to use pure streams, standard C++ provides that.

ok, Thanks, I have solve it by absl::StrFormat().
