Bind parameters to a completion handler, creating a new handler.
        Defined in header <boost/beast/core/bind_handler.hpp>
      
template< class Handler, class... Args> implementation-defined bind_handler( Handler&& handler, Args&&... args);
        This function creates a new handler which, when invoked, calls the original
        handler with the list of bound arguments. Any parameters passed in the invocation
        will be subtituted for placeholders present in the list of bound arguments.
        Parameters which are not matched to placeholders are silently discarded.
        The passed handler and arguments are forwarded into the returned handler,
        which provides the same io_context
        execution guarantees as the original handler.
      
        Unlike boost::asio::io_context::wrap, the returned handler can be used
        in a subsequent call to boost::asio::io_context::post
        instead of boost::asio::io_context::dispatch, to ensure that the handler will
        not be invoked immediately by the calling function.
      
Example:
template<class AsyncReadStream, class ReadHandler> void signal_aborted(AsyncReadStream& stream, ReadHandler&& handler) { boost::asio::post( stream.get_executor(), bind_handler(std::forward<ReadHandler>(handler), boost::asio::error::operation_aborted, 0)); }
