Creates a `Registration`, causing Classroom to start sending notifications from the provided `feed` to the destination provided in `cloudPubSubTopic`. Returns the created `Registration`. Currently, this will be the same as the argument, but with server-assigned fields such as `expiry_time` and `id` filled in. Note that any value specified for the `expiry_time` or `id` fields will be ignored.

This method may return the following error codes: * `PERMISSION_DENIED` if: * the authenticated user does not have permission to receive notifications from the requested field; or * the current user has not granted access to the current Cloud project with the appropriate scope for the requested feed.

Creates a guardian invitation, and sends an email to the guardian asking them to confirm that they are the student's guardian. Once the guardian accepts the invitation, their `state` will change to `COMPLETED` and they will start receiving guardian notifications. A `Guardian` resource will also be created to represent the active guardian. The request object must have the `student_id` and `invited_email_address` fields set. Failing to set these fields, or setting any other fields in the request, will result in an error. This method returns the following error codes: * `PERMISSION_DENIED` if the current user does not have permission to manage guardians, if the guardian in question has already rejected too many requests for that student, if guardians are not enabled for the domain in question, or for other access errors. * `RESOURCE_EXHAUSTED` if the student or guardian has exceeded the guardian link limit. * `INVALID_ARGUMENT` if the guardian email address is not valid (for example, if it is too long), or if the format of the student ID provided cannot be recognized (it is not an email address, nor a `user_id` from this API). This error will also be returned if read-only fields are set, or if the `state` field is set to to a value other than `PENDING`. * `NOT_FOUND` if the student ID provided is a valid student ID, but Classroom has no record of that student. * `ALREADY_EXISTS` if there is already a pending guardian invitation for the student and `invited_email_address` provided, or if the provided `invited_email_address` matches the Google account of an existing `Guardian` for this user.

This method returns the following error codes: * `PERMISSION_DENIED` if the requesting user is not permitted to view guardian invitations for the student identified by the `student_id`, if guardians are not enabled for the domain in question, or for other access errors. * `INVALID_ARGUMENT` if a `student_id` is specified, but its format cannot be recognized (it is not an email address, nor a `student_id` from the API, nor the literal string `me`). * `NOT_FOUND` if Classroom cannot find any record of the given student or `invitation_id`. May also be returned if the student exists, but the requesting user does not have access to see that student.

This method returns the following error codes: * `PERMISSION_DENIED` if a `student_id` is specified, and the requesting user is not permitted to view guardian invitations for that student, if `"-"` is specified as the `student_id` and the user is not a domain administrator, if guardians are not enabled for the domain in question, or for other access errors. * `INVALID_ARGUMENT` if a `student_id` is specified, but its format cannot be recognized (it is not an email address, nor a `student_id` from the API, nor the literal string `me`). May also be returned if an invalid `page_token` or `state` is provided. * `NOT_FOUND` if a `student_id` is specified, and its format can be recognized, but Classroom has no record of that student.

Deletes a guardian. The guardian will no longer receive guardian notifications and the guardian will no longer be accessible via the API. This method returns the following error codes: * `PERMISSION_DENIED` if no user that matches the provided `student_id` is visible to the requesting user, if the requesting user is not permitted to manage guardians for the student identified by the `student_id`, if guardians are not enabled for the domain in question, or for other access errors. * `INVALID_ARGUMENT` if a `student_id` is specified, but its format cannot be recognized (it is not an email address, nor a `student_id` from the API). * `NOT_FOUND` if the requesting user is permitted to modify guardians for the requested `student_id`, but no `Guardian` record exists for that student with the provided `guardian_id`.

Returns a specific guardian. This method returns the following error codes: * `PERMISSION_DENIED` if no user that matches the provided `student_id` is visible to the requesting user, if the requesting user is not permitted to view guardian information for the student identified by the `student_id`, if guardians are not enabled for the domain in question, or for other access errors. * `INVALID_ARGUMENT` if a `student_id` is specified, but its format cannot be recognized (it is not an email address, nor a `student_id` from the API, nor the literal string `me`). * `NOT_FOUND` if the requesting user is permitted to view guardians for the requested `student_id`, but no `Guardian` record exists for that student that matches the provided `guardian_id`.

May also be returned if an invalid `page_token` is provided. * `NOT_FOUND` if a `student_id` is specified, and its format can be recognized, but Classroom has no record of that student.
