module: digital_ocean_snapshot_info
short_description: Gather information about DigitalOcean Snapshot
description:
    - This module can be used to gather information about snapshot information based upon provided values such as droplet, volume and snapshot id.
    - This module was called C(digital_ocean_snapshot_facts) before Ansible 2.9. The usage did not change.
author: "Abhijeet Kasurde (@Akasurde)"
options:
  snapshot_type:
    description:
     - Specifies the type of snapshot information to be retrieved.
     - If set to C(droplet), then information are gathered related to snapshots based on Droplets only.
     - If set to C(volume), then information are gathered related to snapshots based on volumes only.
     - If set to C(by_id), then information are gathered related to snapshots based on snapshot id only.
     - If not set to any of the above, then information are gathered related to all snapshots.
    default: 'all'
    choices: [ 'all', 'droplet', 'volume', 'by_id']
    required: false
  snapshot_id:
    description:
     - To retrieve information about a snapshot, please specify this as a snapshot id.
     - If set to actual snapshot id, then information are gathered related to that particular snapshot only.
     - This is required parameter, if C(snapshot_type) is set to C(by_id).
    required: false
requirements:
  - "python >= 2.6"
