Expand description

MilkyClient 操作中可能发生的错误枚举。

使用 thiserror::Error 宏来自动派生 std::error::Error trait 的实现, 并为每个错误变体提供用户友好的描述信息。

Variants§

§

WebSocket(Box<Error>)

WebSocket 通信过程中发生的错误。 通常由底层的 tokio-tungstenite 库引发。

§

UrlParse(ParseError)

URL 解析失败时发生的错误。 例如,当提供的服务器地址或API端点格式不正确时。

§

UnsupportedScheme(String)

当 URL 使用了不支持的协议方案(scheme)时发生的错误。 例如,客户端可能只支持 “http” 和 “https” (以及对应的 “ws”, “wss”)。

§

Json(Error)

JSON 序列化或反序列化过程中发生的错误。 这可能发生在构造API请求或解析API响应时。

§

Io(Error)

标准输入/输出 (I/O) 操作发生的错误。 例如,在读取配置文件或写入日志时可能发生。

§

ApiError

API 请求失败,通常表示服务器成功处理了请求但返回了一个业务逻辑上的错误。 例如,权限不足、参数错误等。

Fields

§message: String

来自服务器的错误描述信息。

§retcode: Option<i64>

来自服务器的特定返回码(retcode),有助于定位具体错误原因。

§

HttpApiError

HTTP API 请求返回了非成功状态码(例如 4xx, 5xx)。 这表示 HTTP 请求本身可能已发送,但服务器响应了一个 HTTP 错误。

Fields

§status: StatusCode

HTTP 响应的状态码。

§message: String

从服务器响应体中获取的错误信息,或者一个通用的错误描述。

§

NotConnected

表示 WebSocket 连接尚未建立或已经丢失。 尝试在未连接状态下进行需要连接的操作时可能发生。

§

Timeout

操作(如API请求)等待响应超时。

§

UnexpectedResponse

收到了非预期的响应类型。 例如,期望一个特定的JSON结构但收到了其他格式。

§

EchoMismatch

当请求中的 echo 字段与响应中的 echo 字段不匹配时发生。 用于验证异步请求和响应的对应关系。

§

Reqwest(Error)

底层 HTTP 请求库 (reqwest) 发生的错误。 例如,网络连接问题、DNS解析失败等。

§

Internal(String)
