[libcxx-commits] [PATCH] D101752: Speedup to_string for integers using zero-copy.

[Roman Koshelev via Phabricator via libcxx-commits]

Roman-Koshelev added a comment.

As I said

  std::string buf;
  buf.resize(buf.capacity());

with C ++ 20 completely constexpr and equivalent

  char buf[bufsize];

It is also obvious that

  string(buf, res.ptr);

worse than

  buf.resize(res.ptr - buf.data());
