# Tauri 命名规范文档
|
||
|
||
## 概述
|
||
|
||
本文档定义了 SSH Terminal 项目中 Tauri 应用 Rust 端和前端(TypeScript/JavaScript)之间的数据类型命名规范。通过遵循这些规范,可以确保跨语言的类型安全性和一致性。
|
||
|
||
## 核心原则
|
||
|
||
### 1. 各自遵循语言规范
|
||
- **Rust 端**: 遵循 Rust 命名规范(snake_case 变量/函数,PascalCase 类型/枚举)
|
||
- **前端**: 遵循 TypeScript 命名规范(camelCase 变量/属性,PascalCase 类型)
|
||
- **通过 serde 自动转换**: 使用 `serde` 的重命名功能自动处理转换
|
||
|
||
### 2. 类型名称保持一致
|
||
- **Rust 端**: PascalCase(如 `SessionConfig`, `AuthMethod`)
|
||
- **前端**: PascalCase(如 `SessionConfig`, `AuthMethod`)
|
||
- 类型名称在两端保持一致
|
||
|
||
## 详细规范
|
||
|
||
### Struct 字段命名
|
||
|
||
#### Rust 端规范
|
||
- 使用 **snake_case** 命名
|
||
- 添加 `#[serde(rename_all = "camelCase")]` 注解自动转换为 camelCase
|
||
|
||
```rust
|
||
#[derive(Serialize, Deserialize)]
|
||
#[serde(rename_all = "camelCase")]
|
||
pub struct SessionConfig {
|
||
pub host: String, // Rust: snake_case
|
||
pub port: u16,
|
||
pub user_name: String, // Rust: snake_case
|
||
pub private_key_path: String, // Rust: snake_case
|
||
pub auth_method: AuthMethod,
|
||
}
|
||
```
|
||
|
||
#### 前端规范
|
||
- 使用 **camelCase** 命名
|
||
- 与 serde 自动转换后的名称一致
|
||
|
||
```typescript
|
||
export interface SessionConfig {
|
||
host: string; // TS: camelCase
|
||
port: number;
|
||
userName: string; // TS: camelCase
|
||
privateKeyPath: string; // TS: camelCase
|
||
authMethod: AuthMethod;
|
||
}
|
||
```
|
||
|
||
### Enum 变体命名
|
||
|
||
#### Rust 端规范
|
||
- 使用 **PascalCase** 命名
|
||
- 添加 `#[serde(rename_all = "camelCase")]` 注解自动转换为 camelCase
|
||
|
||
```rust
|
||
#[derive(Serialize, Deserialize)]
|
||
#[serde(rename_all = "camelCase")]
|
||
pub enum AuthMethod {
|
||
Password { password: String }, // PascalCase
|
||
PublicKey { privateKeyPath: String, passphrase: Option<String> },
|
||
}
|
||
```
|
||
|
||
#### 前端规范
|
||
- 使用 **PascalCase** 命名(Discriminated Union)
|
||
- 与 serde 自动转换后的变体名称一致
|
||
|
||
```typescript
|
||
export type AuthMethod =
|
||
| { Password: { password: string } } // PascalCase
|
||
| { PublicKey: { privateKeyPath: string; passphrase?: string } };
|
||
```
|
||
|
||
### 字段命名对照表
|
||
|
||
| Rust 端 (snake_case) | 前端 (camelCase) | 示例用途 |
|
||
|---------------------|------------------|---------|
|
||
| `user_name` | `userName` | 用户名 |
|
||
| `private_key_path` | `privateKeyPath` | 私钥路径 |
|
||
| `auth_method` | `authMethod` | 认证方法 |
|
||
| `connection_id` | `connectionId` | 连接 ID |
|
||
| `terminal_type` | `terminalType` | 终端类型 |
|
||
| `keep_alive_interval` | `keepAliveInterval` | 保活间隔 |
|
||
| `strict_host_key_checking` | `strictHostKeyChecking` | 主机密钥检查 |
|
||
| `video_file` | `videoFile` | 视频文件 |
|
||
|
||
## 特殊情况处理
|
||
|
||
### 1. 保留字段原名
|
||
如果某些字段需要保持原名(通常是已经是 camelCase 的字段),可以使用 `#[serde(skip_serializing_if = "Option::is_none")]` 或单独注解:
|
||
|
||
```rust
|
||
#[derive(Serialize, Deserialize)]
|
||
#[serde(rename_all = "camelCase")]
|
||
pub struct SessionConfig {
|
||
pub name: String, // name -> name (保持不变)
|
||
#[serde(rename = "id")] // 显式重命名
|
||
pub session_id: String,
|
||
}
|
||
```
|
||
|
||
### 2. 单词分隔符
|
||
- **snake_case**: 使用下划线 `_` 分隔
|
||
- **camelCase**: 使用首字母大写分隔
|
||
|
||
```rust
|
||
// Rust: strict_host_key_checking
|
||
// TS: strictHostKeyChecking
|
||
```
|
||
|
||
### 3. 缩写处理
|
||
- 缩写词保持原始形式(如 `ID`, `URL`, `SSH`)
|
||
- 不要将缩写词转换为小写
|
||
|
||
```rust
|
||
pub connection_id: String, // NOT connection_i_d
|
||
// TS: connectionId // NOT connectionId
|
||
```
|
||
|
||
## 实现示例
|
||
|
||
### Rust 端完整示例
|
||
|
||
```rust
|
||
use serde::{Serialize, Deserialize};
|
||
|
||
#[derive(Serialize, Deserialize, Clone, Debug)]
|
||
#[serde(rename_all = "camelCase")]
|
||
pub struct SessionConfig {
|
||
pub id: Option<String>,
|
||
pub name: String,
|
||
pub host: String,
|
||
pub port: u16,
|
||
pub username: String,
|
||
pub authMethod: AuthMethod,
|
||
pub terminalType: Option<String>,
|
||
pub columns: Option<u16>,
|
||
pub rows: Option<u16>,
|
||
#[serde(default = "default_strict_host_key_checking")]
|
||
pub strictHostKeyChecking: bool,
|
||
#[serde(default = "default_group")]
|
||
pub group: String,
|
||
#[serde(default = "default_keep_alive_interval")]
|
||
pub keepAliveInterval: u64,
|
||
}
|
||
|
||
#[derive(Serialize, Deserialize, Clone, Debug)]
|
||
#[serde(rename_all = "camelCase")]
|
||
pub enum AuthMethod {
|
||
Password { password: String },
|
||
PublicKey { privateKeyPath: String, passphrase: Option<String> },
|
||
}
|
||
```
|
||
|
||
### 前端完整示例
|
||
|
||
```typescript
|
||
export interface SessionConfig {
|
||
id?: string;
|
||
name: string;
|
||
host: string;
|
||
port: number;
|
||
username: string;
|
||
authMethod: AuthMethod;
|
||
terminalType?: string;
|
||
columns?: number;
|
||
rows?: number;
|
||
strictHostKeyChecking?: boolean;
|
||
group?: string;
|
||
keepAliveInterval?: number;
|
||
}
|
||
|
||
export type AuthMethod =
|
||
| { Password: { password: string } }
|
||
| { PublicKey: { privateKeyPath: string; passphrase?: string } };
|
||
```
|
||
|
||
## 验证和测试
|
||
|
||
### 1. Rust 端验证
|
||
```bash
|
||
cd src-tauri
|
||
cargo check
|
||
cargo clippy
|
||
```
|
||
|
||
### 2. 前端验证
|
||
```bash
|
||
pnpm tsc --noEmit
|
||
```
|
||
|
||
### 3. 交叉验证
|
||
- 测试 Rust 序列化到 JSON
|
||
- 验证前端反序列化是否正确
|
||
- 检查字段名是否匹配
|
||
|
||
## 常见错误
|
||
|
||
### 错误 1: 未添加 serde 注解
|
||
```rust
|
||
// ❌ 错误
|
||
pub struct SessionConfig {
|
||
pub user_name: String, // 序列化为 user_name (snake_case)
|
||
}
|
||
|
||
// ✅ 正确
|
||
#[derive(Serialize, Deserialize)]
|
||
#[serde(rename_all = "camelCase")]
|
||
pub struct SessionConfig {
|
||
pub user_name: String, // 序列化为 userName (camelCase)
|
||
}
|
||
```
|
||
|
||
### 错误 2: 前端类型不匹配
|
||
```typescript
|
||
// ❌ 错误
|
||
export interface SessionConfig {
|
||
user_name: string; // 应该是 userName
|
||
}
|
||
|
||
// ✅ 正确
|
||
export interface SessionConfig {
|
||
userName: string; // 与 Rust 端序列化后的名称一致
|
||
}
|
||
```
|
||
|
||
### 错误 3: Enum 变体命名不一致
|
||
```rust
|
||
// ❌ 错误
|
||
pub enum AuthMethod {
|
||
Password, // 序列化为 "Password" (PascalCase)
|
||
PublicKey,
|
||
}
|
||
|
||
// ✅ 正确
|
||
#[derive(Serialize, Deserialize)]
|
||
#[serde(rename_all = "camelCase")]
|
||
pub enum AuthMethod {
|
||
Password, // 序列化为 "password" (camelCase)
|
||
PublicKey, // 序列化为 "publicKey" (camelCase)
|
||
}
|
||
```
|
||
|
||
## 工具和辅助
|
||
|
||
### 自动检查脚本
|
||
可以创建一个脚本来检查 Rust 和前端类型定义的一致性:
|
||
|
||
```bash
|
||
# 检查 Rust 端是否缺少 serde 注解
|
||
grep -r "pub struct" src-tauri/src | grep -v "#\[serde"
|
||
|
||
# 检查前端类型定义
|
||
grep -r "export interface" src/types
|
||
```
