package awss3


// Specifies when noncurrent object versions expire.
//
// Upon expiration, Amazon S3 permanently deletes the noncurrent object versions. You set this lifecycle configuration action on a bucket that has versioning enabled (or suspended) to request that Amazon S3 delete noncurrent object versions at a specific period in the object's lifetime. For more information about setting a lifecycle rule configuration, see [AWS::S3::Bucket Rule](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-s3-bucket-lifecycleconfig-rule.html) .
