type InitFunction func() (interface{}, error)
type ConnectionPoolWrapper struct {

Call the init function size times. If the init function fails during any call, then
the creation of the pool is considered a failure.

通讯协议规范

新 RPC 服务器采用自定义文本协议,并满足以下条件:

  1. 可以在各种语言中简单的实现
  2. 能被快速解析
  3. 方便 Telnet 调试

相对于二进制协议,新 RPC 服务器的文本协议议具有较高的可读性,也容易被实现, 减少在客户端实现中出现BUG,并且解析性可以做到与二进制协议接近。
