Pool是一个线程安全，针对net.Conn接口的连接池。它可用于管理和复用网络连接。
示例：
// create a factory() to be used with channel based pool factory := func() (net.Conn, error) { return net.Dial("tcp", "127.0.0.1:4000") } // create a new channel based pool with an initial capacity of 5 and maximum // capacity of 30. The factory will create 5 initial connections and put it // into the pool. p, err := pool.NewChannelPool(5, 30, factory) // now you can get a connection from the pool, if there is no connection // available it will create a new one via the factory function. conn, err := p.Get() // do something with conn and put it back to the pool by closing the connection // (this doesn't close the underlying connection instead it's putting it back // to the pool). conn.Close() // close pool any time you want, this closes all the connections inside a pool p.Close() // currently available connections in the pool current := p.Len()
