Functions

func RegisterRPCResultHandler 

func RegisterRPCResultHandler(responseAck string, handler func() RpcResponseResult)

RegisterRPCResultHandler registers an external RPC that's not including in pegasus-go-client.

The following example registers an response handler for Pegasus's remote-command RPC. Usage:

```go 

RegisterRpcResultHandler("RPC_CLI_CLI_CALL_ACK", func() RpcResponseResult {
  return &RemoteCmdServiceCallCommandResult{Success: new(string)}
})

```

func ResolveMetaAddr 

func ResolveMetaAddr(addrs []string) ([]string, error)

ResolveMetaAddr into a list of TCP4 addresses. Error is returned if the given `addrs` are not either a list of valid TCP4 addresses, or a resolvable hostname.

const (
	// NodeTypeMeta indicates it's a session to MetaServer.
