module Aws
# Create and provide access to components of Amazon Resource Names (ARN).
#
# You can create an ARN and access it's components like the following:
#
# arn = Aws::ARN.new(
# partition: 'aws',
# service: 's3',
# region: 'us-west-2',
# account_id: '12345678910',
# resource: 'foo/bar'
# )
# # => #<Aws::ARN ...>
#
# arn.to_s
# # => "arn:aws:s3:us-west-2:12345678910:foo/bar"
#
# arn.partition
# # => 'aws'
# arn.service
# # => 's3'
# arn.resource
# # => foo/bar
#
# # Note: parser available for parsing resource details
# @see Aws::ARNParser#parse_resource
#
# @see https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html#genref-arns
