-- Amazon Elastic Container Registry
--
-- Amazon Elastic Container Registry (Amazon ECR) is a managed container
-- image registry service. Customers can use the familiar Docker CLI, or
-- their preferred client, to push, pull, and manage images. Amazon ECR
-- provides a secure, scalable, and reliable registry for your Docker or
-- Open Container Initiative (OCI) images. Amazon ECR supports private
-- repositories with resource-based permissions using IAM so that specific
-- users or Amazon EC2 instances can access repositories and images.
--
-- Amazon ECR has service endpoints in each supported Region. For more
-- information, see
-- <https://docs.aws.amazon.com/general/latest/gr/ecr.html Amazon ECR endpoints>
-- in the /Amazon Web Services General Reference/.

-- $errors
-- Error matchers are designed for use with the functions provided by
-- <http://hackage.haskell.org/package/lens/docs/Control-Exception-Lens.html Control.Exception.Lens>.
-- This allows catching (and rethrowing) service specific errors returned
-- by 'ECR'.

-- $operations
-- Some AWS operations return results that are incomplete and require subsequent
-- requests in order to obtain the entire result set. The process of sending
-- subsequent requests to continue where a previous request left off is called
-- pagination. For example, the 'ListObjects' operation of Amazon S3 returns up to
-- 1000 objects at a time, and you must send subsequent requests with the
-- appropriate Marker in order to retrieve the next page of results.
--
-- Operations that have an 'AWSPager' instance can transparently perform subsequent
-- requests, correctly setting Markers and other request facets to iterate through
-- the entire result set of a truncated API operation. Operations which support
-- this have an additional note in the documentation.
--
-- Many operations have the ability to filter results on the server side. See the
-- individual operation parameters for details.

-- $waiters
-- Waiters poll by repeatedly sending a request until some remote success condition
-- configured by the 'Wait' specification is fulfilled. The 'Wait' specification
-- determines how many attempts should be made, in addition to delay and retry strategies.
