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_DeleteRecoveryPoint.go
    path of file: ./repos/aws-sdk-go-v2/service/backup
    
    the code of the file until where you have to start completion: // Code generated by smithy-go-codegen DO NOT EDIT.

package backup

// Deletes the recovery point specified by a recovery point ID. If the recovery
// point ID belongs to a continuous backup, calling this endpoint deletes the
// existing continuous backup and stops future continuous backup. When an IAM
// role's permissions are insufficient to call this API, the service sends back an
// HTTP 200 response with an empty HTTP body, but the recovery point is not
// deleted. Instead, it enters an EXPIRED state. EXPIRED recovery points can be
// deleted with this API once the IAM role has the iam:CreateServiceLinkedRol
