You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: api_op_CreateConnection.go
    path of file: ./repos/aws-sdk-go-v2/service/directconnect
    
    the code of the file until where you have to start completion: // Code generated by smithy-go-codegen DO NOT EDIT.

// Creates a connection between a customer network and a specific Direct Connect
// location. A connection links your internal network to an Direct Connect location
// over a standard Ethernet fiber-optic cable. One end of the cable is connected to
// your router, the other to an Direct Connect router. To find the locations for
// your Region, use DescribeLocations . You can automatically add the new
// connection to a link aggregation group (LAG) by specifying a LAG ID in the
// request. This ensures that the new connection is allocated on the same Direct
// Connect endpoint that hosts the specified LAG. If there are no available ports
// on the endpoint, the request fails and no connection is created.
