Throws MYX upon failure to connect.

If you are using Vibe.d, consider using mysql.pool.MySQLPool instead of creating a new Connection directly. That will provide certain benefits, such as reusing old connections and automatic cleanup (no need to close the connection when done). 

// Suggested usage:

{
    auto con = new Connection("host=localhost;port=3306;user=joe;pwd=pass123;db=myappsdb");
    scope(exit) con.close();

    // Use the connection
    ...
}

Parameters

NameDescription
cs A connection string of the form "host=localhost;user=user;pwd=password;db=mysqld" (TODO: The connection string needs work to allow for semicolons in its parts!)
socketType Whether to use a Phobos or Vibe.d socket. Default is Phobos, unless compiled with -version=Have_vibe_core (set automatically if using DUB).
openSocket Optional callback which should return a newly-opened Phobos or Vibe.d TCP socket. This allows custom sockets to be used, subclassed from Phobos's or Vibe.d's sockets.
host An IP address in numeric dotted form, or as a host name.
user The user name to authenticate.
pwd User's password.
db Desired initial database.
capFlags The set of flag bits from the server's capabilities that the client requires
