module: restconf_config
version_added: "2.8"
author: "Ganesh Nalawade (@ganeshrn)"
short_description: Handles create, update, read and delete of configuration data on RESTCONF enabled devices.
description:
    - RESTCONF is a standard mechanisms to allow web applications to configure and manage
      data. RESTCONF is a IETF standard and documented on RFC 8040.
    - This module allows the user to configure data on RESTCONF enabled devices.

      - URI being used to execute API calls.
    required: true
  content:
    description:
      - The configuration data in format as specififed in C(format) option. Required unless C(method) is
        I(delete).
  method:
    description:
      - The RESTCONF method to manage the configuration change on device. The value I(post) is used to
        create a data resource or invoke an operation resource, I(put) is used to replace the target
        data resource, I(patch) is used to modify the target resource, and I(delete) is used to delete
        the target resource.
    required: false
    default: post
    choices: ['post', 'put', 'patch', 'delete']
