Struct Res 

pub struct Res<T: Serialize = ()> {
    pub code: i32,
    pub msg: String,
    pub data: Option<T>,
}

统一 API 响应结构

Fields

code: i32

业务码，0 表示成功

msg: String

提示信息

data: Option<T>

数据载荷

Implementations

impl Res<()>

pub fn ok_empty() -> Self

成功（无数据载荷），返回 {code: 0, msg: "ok", data: null}

pub fn ok_msg(msg: impl Into<String>) -> Self

成功（自定义消息，无数据载荷）

impl<T: Serialize> Res<T>

pub fn ok(data: T) -> Self

成功响应，携带数据载荷

示例

Res::ok(user)          // => {code: 0, msg: "ok", data: user}
Res::ok("hello")       // => {code: 0, msg: "ok", data: "hello"}

pub fn ok_with_msg(data: T, msg: impl Into<String>) -> Self

成功响应，携带数据载荷和自定义消息

pub fn fail(code: i32, msg: impl Into<String>) -> Self

失败响应（自定义错误码和消息，无数据载荷）

示例

Res::fail(codes::BAD_REQUEST, "用户名不能为空")

impl<T: Serialize> Res<PageData<T>>

pub fn page(list: T, total: u64, page: u64, page_size: u64) -> Self

分页响应
