golang tcp 连接池工具

参考使用

// 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 the underlying connection instead of returning it to pool

// it is useful when acceptor has already closed connection and conn.Write() returns error

if pc, ok := conn.(*pool.PoolConn); ok {

  pc.MarkUnusable()

  pc.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()
