module: rds_snapshot_info
version_added: "2.6"
short_description: obtain information about one or more RDS snapshots
description:
  - obtain information about one or more RDS snapshots. These can be for unclustered snapshots or snapshots of clustered DBs (Aurora)
  - Aurora snapshot information may be obtained if no identifier parameters are passed or if one of the cluster parameters are passed.
  - This module was called C(rds_snapshot_facts) before Ansible 2.9. The usage did not change.
options:
