error: no matching function for call to ‘boost::asio::mutable_buffer::mutable_buffer(const boost::asio::const_buffers_1&)’
The weird thing is that following code compiles:
auto b1 = asio::buffer(getRecvBuffer());
Following code compiles too:
auto buf = client.socketRecvBuffer_.recvBuffer();
socket_.async_receive(asio::buffer(buf), [](auto&&...) {});
It seems in order to create a mutable_buffer, I need a lvalue for the buffer, which makes sense in case of std::vector, but it does not make sense for boost::span.
I have a function that returns a buffer as a span to read the data from socket:
When I call
tcp::socket::async_receive(asio::buffer(getRecvBuffer()))
,... I get an error:
