The follow is the ring's source, and I am a newbie in Clojure.
what the defn of run-jetty looks like this form, what's the meaning of
#^Server in the defn and let?
Thanks in advance.
Limux.
(defn #^Server run-jetty
"Serve the given handler according to the options.
Options:
:configurator - A function called with the Server instance.
:port
:host
:join? - Block the caller: defaults to true.
:ssl? - Use SSL.
:ssl-port - SSL port: defaults to 443, implies :ssl?
:keystore
:key-password
:truststore
:trust-password"
[handler options]
(let [#^Server s (create-server (dissoc options :configurator))]
(when-let [configurator (:configurator options)]
(configurator s))
(doto s
(.setHandler (proxy-handler handler))
(.start))
(when (:join? options true)
(.join s))
s))
