Copy a streambuf's contents to a string

Question

Apparently boost::asio::async_read doesn\'t like strings, as the only overload of boost::asio::buffer allows me to create const_buffer

Answer 1

I mostly don't like answers that say "You don't want X, you want Y instead and here's how to do Y" but in this instance I'm pretty sure I know what tstenner wanted.

In Boost 1.66, the dynamic string buffer type was added so async_read can directly resize and write to a string buffer.
