golang中是否有任何等效的滑动缓冲区chan？

Question

In clojure we can have sliding-buffer chan; Is there any equivalent in golang?

(require '[clojure.core.async :refer [go-loop <! >!! sliding-buffer chan]])
(def sliding-chan (chan (sliding-buffer 1)))
(go-loop []
  (println "Received:" (<! sliding-chan))
  (recur))
(dotimes [n 100]
  (>!! sliding-chan n))

;;=> Received: 0 
;;=> Received: 99

I don't think so. Go has buffered channels but they will block when the channel is full.

You'll probably have to write something yourself, maybe with a goroutine in the middle that manages the buffer (maybe using deque ;)
