feat: add send for room by adding talkable trait

[7sDream]

通过增加一个 Talkable trait 给 Room 增加了 send_xxx 系列方法，复用的 Contract 里的实现。

因为不知道 wechaty 的具体架构和协议，不太确定有没有问题，测试了 room.send_text 是没问题的。

另外不知道是客户端这边实现确实不对，还是 wechaty-puppet-wechat 实现有问题，用 wechaty docker 镜像 0.63 版本作为 puppet，扫码登录时会发一个 Heartbeat 类型的消息过来，但是 data 字段是个 Object（而不是代码里定义的 String），会导致 panic，这里顺便修复了下。

还有点小修改，比如给 QueryFilter 类型都加上了 Default trait 方便构造 filter。

以下是 Heartbeat 的 data 为 Object 的 Log：

@7sDream Thanks a lot for your contribution!

The data type of the heartbeat message may have been changed since there have been several months since I last worked on this project.

[lucifer1004]

Have you checked the message sending/receiving functions? Did they work?

Just tested the room.send_text, it works. Other type like send_contract/url/... has not been tested. But I can test it some time in today night.

Since my own bot didn't need receive message , I haven't tested it either. But I don’t think I changed any code for receiving messages.

@huan What is the exact type of the data field in RPC messages right now?

[7sDream]

Just added a example log screenshot for Heartbeat event data filed type is object.

@huan What is the exact type of the data field in RPC messages right now?

If you are referring to the payload, I believe it should be a string.

Please see the proto buffer definition at https://github.com/wechaty/grpc/blob/9c4d6c91540db9fafc74b9bc1b5fc616beaa4526/proto/wechaty/puppet/event.proto#L36

@huan Please have a look at the screenshot posted by @7sDream, in which a Heartbeat message's payload had a non-string data field.

@huan Please have a look at the screenshot posted by @7sDream, in which a Heartbeat message's payload had a non-string data field.

According to the gRPC which is based on proto buffer protocol, the payload can only be string type.

It might be a stringified objects json string.

However, I do not know if there's any additional operations in the rust code. Please check it and let me know if there's anything I can help.

[7sDream]

payload was defined in proto file, which should(and do) always be a string, a JSON string.

When parse(deserialize) payload into a struct, it has a data field.

In many condition, data field is a String, but in Heartbeat event triggered by scanning the login qrcode(but has not clicked confirm login button on the phone), data is a Object, just like screenshot shows.

The spec of this data field cannot be seen from the proto definition.

LGTM

Yes, that's correct.

The spec of this data field cannot be seen from the proto definition.

I don't think we have a spec for this data field. Please correct me if I'm not right.

I believe the data could be any data which highly depends on the specific logic.

P.S. I agree that the heartbeat event should send simple data, I will inspect the related server code later.
