-- This operation lists all vaults owned by the calling user\'s account.
-- The list returned in the response is ASCII-sorted by vault name.
--
-- By default, this operation returns up to 1,000 items. If there are more
-- vaults to list, the response 'marker' field contains the vault Amazon
-- Resource Name (ARN) at which to continue the list with a new List Vaults
-- request; otherwise, the 'marker' field is 'null'. To return a list of
-- vaults that begins at a specific vault, set the 'marker' request
-- parameter to the vault ARN you obtained from a previous List Vaults
-- request. You can also limit the number of vaults returned in the
-- response by specifying the 'limit' parameter in the request.
--
-- An AWS account has full permission to perform all operations (actions).
-- However, AWS Identity and Access Management (IAM) users don\'t have any
-- permissions by default. You must grant them explicit permission to
-- perform specific actions. For more information, see
-- <http://docs.aws.amazon.com/amazonglacier/latest/dev/using-iam-with-amazon-glacier.html Access Control Using AWS Identity and Access Management (IAM)>.
