Walle-core 是一个 Rust OneBot Lib ( 不同于 libonebot 他同样可以应用于 OneBot 应用端 )
Walle 的名字来源于机械总动员的 WALL-E ( A Rusty Bot )
## 功能
- 提供 OneBot v12 标准 Event、Action、ActionResp 序列化与反序列化功能,并支持自定义扩展
- 提供 OneBot v12 实现端标准网络通讯协议
- 提供 OneBot v12 应用端标准网络通讯协议(Http HttpWebhook 未支持)
## features
- http: 启用 Http 与 HttpWebhook 通讯协议
- websocket: 启用正向 WebSocket 与反向 WebSocket 通讯协议
- impl-obc: 启用实现端 obc
- app-obc: 启用应用端 obc
- alt: 启用 ColoredAlt trait 着色输出纯文本 alt
- full: 启用所有 features
## How to use
仅展示最小实例
### Implementation
```rust
use std::sync::Arc;
use walle_core::action::Action;
use walle_core::alt::TracingHandler;
use walle_core::config::ImplConfig;
use walle_core::event::Event;
use walle_core::obc::ImplOBC;
use walle_core::resp::Resp;
use walle_core::OneBot;
#[tokio::main]
async fn main() {
tracing_subscriber::fmt::init();
let ob = Arc::new(OneBot::new(
TracingHandler::::default(),
ImplOBC::new("impl".to_string()),
));
let tasks = ob.start((), ImplConfig::default(), true).await.unwrap();
for task in tasks {
task.await.unwrap()
}
}
```
### Application
```rust
use std::sync::Arc;
use walle_core::action::Action;
use walle_core::alt::TracingHandler;
use walle_core::config::AppConfig;
use walle_core::event::Event;
use walle_core::obc::AppOBC;
use walle_core::resp::Resp;
use walle_core::OneBot;
#[tokio::main]
async fn main() {
tracing_subscriber::fmt::init();
let ob = Arc::new(OneBot::new(
AppOBC::new(),
TracingHandler::::default(),
));
let tasks = ob.start(AppConfig::default(), (), true).await.unwrap();
for task in tasks {
task.await.unwrap()
}
}
```
### Event
walle_core::event::Event 为序列化使用标准类型,该模型仅确保 event 基础模型各字段。
walle_core::event::BaseEvent\ 为扩展模型,其中五个泛型依次为 type detail_type sub_type platform impl 五个层级的扩展字段
需要实现 Event -> BaseEvent 转化时,扩展字段需要 impl `TryFromEvent` trait ,通常在应用端使用
需要实现 BaseEvent -> Event 转化时,扩展字段需要 impl `PushtoValueMap` 和 `ToEvent` trait ,通常在协议端使用
> 其中 T 标识不同扩展级别,分别为 `TypeLevel` | `DetailTypeLevel` | `SubTypeLevel` | `PlatformLevel` | `ImplLevel`
或者直接使用本 crate 提供的派生宏
定义一个 type 级别扩展字段( ob12 理论上不支持该级别扩展):
```rust
use walle_core::prelude::{PushToValueMap, ToEvent, TryFromEvent};
#[derive(ToEvent, PushToValueMap, TryFromEvent)]
#[event(type)]
pub struct Message {
pub message_id: String,
pub message: crate::message::Message,
pub alt_message: String,
pub user_id: String,
}
```
或者定义一个 detail_type 级别扩展字段
```rust
#[derive(PushToValueMap, TryFromEvent, ToEvent)]
#[event(detail_type = "group")]
pub struct Group_ {
pub group_id: String,
}
// TryFromEvent 支持 enum 类型的扩展
#[derive(TryFromEvent)]
#[event(detail_type)]
pub enum Details {
Group(Group), // Group 应 impl TryFromValue
Private,
}
```
### Action
walle_core::action::Action 为序列化使用标准类型,该模型仅确保 action 与 params 字段存在且类型正确
实现 Action -> BaseAction 或 Action -> T 转化时,扩展字段需要 impl `TryFromAction` trait
实现 BaseAction -> Action 或 T -> Action 转化时,扩展字段需要 impl `PushtoValueMap` 和 `ToAction` trait
或者直接使用本 crate 提供的派生宏
```rust
#[derive(ToAction, PushToValueMap, TryFromAction)]
pub struct GetFile {
pub file_id: String,
pub ty: String,
}
```
或者
```rust
#[derive(ToAction, TryFromAction, PushToValueMap)]
#[action("upload_file")]
pub struct UploadFile_ {
pub ty: String,
pub name: String,
pub url: Option,
pub headers: Option>,
pub path: Option,
pub data: Option,
pub sha256: Option,
}
```
想要同时支持多种 Action ? 没问题!
```rust
#[derive(TryFromAction)]
pub enum MyAction {
GetUserInfo(GetUserInfo), // GetUserInfo 应 impl TryFromValue
GetGroupInfo { group_id: String },
}
```
### Resp (Value)
walle_core::resp::Resp 为序列化使用标准类型
同时本库还提供了 RespError 用于构造失败的 Resp,可以使用 \.as_result()
实现 Value -> T 转化时,需要 impl `TryFromValue` trait
实现 T -> Value 转化时,需要 impl `PushToValueMap` trait (仅支持 struct )
当然还是可以使用宏
```rust
#[derive(PushToValueMap, TryFromValue)]
pub struct Status {
pub good: bool,
pub online: bool,
}
```
同时实现了 Value 的结构体可以作为其他宏的字段使用。
### MessageSegment
基本与 Action 模型相同,唯一的不同是序列化使用的模型是 walle_core::message::MessageSegment,该模型同时也是一个 Value ,因此可以从 Event 或 Action 中获取。
```rust
#[derive(PushToValueMap, TryFromMsgSegment, ToMsgSegment)]
pub struct Text {
pub text: String,
}
```
### Notice
由于与 Rust 保留字冲突,宏将会对以下字段自动转义:
- `"type"` -> `ty`
- `"impl"` -> `implt`
- `"selft"` -> `self`
