Performs the MySQL-level handshake.
template< class CompletionToken> auto async_handshake( consthandshake_params
& params,diagnostics
& diag, CompletionToken&& token);
Does not connect the underlying stream. If the Stream
template parameter fulfills the SocketConnection
requirements, use connection::connect
instead of this function.
If using a SSL-capable stream, the SSL handshake will be performed by this function.
The strings pointed to by params
should be kept alive by the caller until the operation completes, as
no copy is made by the library.
The handler signature for this operation is void(boost::mysql::error_code)
.
Intermediate completion handlers, as well as the final handler, are executed
using token
's associated
executor, or this->get_executor()
if the token doesn't have an associated executor.
If the final handler has an associated immediate executor, and the operation
completes immediately, the final handler is dispatched to it. Otherwise,
the final handler is called as if it was submitted using asio::post
, and is never be called inline
from within this function.
