-- Returns all the crawls of a specified crawler. Returns only the crawls
-- that have occurred since the launch date of the crawler history feature,
-- and only retains up to 12 months of crawls. Older crawls will not be
-- returned.
--
-- You may use this API to:
--
-- -   Retrive all the crawls of a specified crawler.
--
-- -   Retrieve all the crawls of a specified crawler within a limited
--     count.
--
-- -   Retrieve all the crawls of a specified crawler in a specific time
--     range.
--
-- -   Retrieve all the crawls of a specified crawler with a particular
--     state, crawl ID, or DPU hour value.
