-- | The Lambda function to delete.
--
-- You can specify an unqualified function name (for example, "Thumbnail") or
-- you can specify Amazon Resource Name (ARN) of the function (for example,
-- "arn:aws:lambda:us-west-2:account-id:function:ThumbNail"). AWS Lambda also
-- allows you to specify only the account ID qualifier (for example,
-- "account-id:Thumbnail"). Note that the length constraint applies only to the
-- ARN. If you specify only the function name, it is limited to 64 character in
-- length.
