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

// UpdateContinuousBackups enables or disables point in time recovery for the
// specified table. A successful UpdateContinuousBackups call returns the current
// ContinuousBackupsDescription . Continuous backups are ENABLED on all tables at
// table creation. If point in time recovery is enabled, PointInTimeRecoveryStatus
// will be set to ENABLED. Once continuous backups and point in time recovery are
// enabled, you can restore to any point in time within EarliestRestorableDateTime
// and LatestRestorableDateTime . LatestRestorableDateTime is typically 5 minutes
// before the current time. You can restore your table to any point in time during
// the last 35 days.
